10 Inspiring Carl Sagan Quotes That Will Change Your Life

Carl Sagan was an American scientist who is best known for Cosmos: a personal voyage in which he kindled a public curiosity about science and astronomy through television. He became an inspiration for many aspiring students, including future astrophysicist Neil deGrasse Tyson.

Other than being an advisor to NASA, Carl Sagan also wrote award winning books, such as Dragons of Eden which won the Pulitzer Prize, and made sci-fi films, like Contact starring Jodie Foster and Matthew McConaughey.

Following are 10 quotes by Carl Sagan which will not only open your mind, but also change your life for real.

1. Somewhere, something incredible is waiting to be known.

This quote encourages us to explore the unknown with excitement. Many a times doctoral students lose hope because what an arduous journey it is to get a PhD. But Carl Sagan says there is always something new to discover, if we do not give up.

2. The cosmos is within us. We are made of star-stuff. We are a way for the cosmos to know itself.

A reminder that we are part of something much bigger, encouraging us to embrace our potential, which may now be hidden or dormant, and to explore our connection to the universe. It links personal ambition to grandeur of the universe.

3. Imagination will often carry us to worlds that never were. But without it, we go nowhere.

 

This quote is similar to Einstein's imagination is more important than knowledge. It is highlighting the power of creative thinking. In any sphere of life, imagination and creativity are of paramount importance.

4. For small creatures such as we, the vastness is bearable only through love.

This quote is my favorite. We are like butterflies who flutter for a day and think it is forever. This motivates students to find strength in connection and passion. Sagan believes that the power of love is a great motivating force, especially when faced with the enormity of existence.

5. The brain is like a muscle. When it is in use, we feel very good. Understanding is joyous.

Carl Sagan understands the significance of acquiring knowledge, celebrating the thrill of intellectual effort.

6. It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.

It is crucial for students to be critical, logical and inquisitive. This quote is urging students to seek truth over comfort.

7. We are star stuff which has taken its destiny into its own hands.

What a beautiful thought isn't it? This quote by Carl Sagan encourages self-empowerment, reinforcing that we have the potential to shape our own futures. Destiny is created.

8. We make our world significant by the courage of our questions and the depth of our answers.

This quote is pushing students to ask hard questions and seek profound solutions. The world only changes and evolves if we keep asking questions to authority unafraid. This passion, is precious....

9. The universe is not required to be in perfect harmony with human ambition.

..... however, passion may not always lead to the solutions we want. This quote is a reminder that the universe doesn't cater to our desires, so we must find our own path and purpose in the world. In our capacity we should do what we can without worrying about the result.

10. In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with you.

This Carl Sagan quote is a reminder that we only live once. Seize the moment and connect with others in the journey of learning. Do not wait for the next opportunity in the future while the present waits for you. Time is slipping away at the passing of every thought which did not turn into action.

9 Quotes By Carl Sagan On Astronomy

Carl Sagan was an American scientist (1934-1996) who is best known for his TV show Cosmos: a personal voyage and inspiring astrophysicists like Neil deGrasse Tyson to pursue astronomy. Carl Sagan was an expert in the field of exobiology and search for extraterrestrial life.

Carl Sagan also worked with NASA on various projects including the Pioneer plaque and Voyager golden record, which were the first physical messages sent to space. Since Carl Sagan was born on November 9, celebrated as Carl Sagan day across America, following are 9 quotes on astronomy by Carl Sagan:

1. The cosmos is within us. We're made of star stuff. We are a way for the cosmos to know itself.

2. Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

3. For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.

4. Virtually every newspaper in America has a daily column on astrology; there are hardly any that have even a weekly column on astronomy.

5. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark.

6. I stress that the universe is made mostly of nothing, that something is the exception.

7. A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.

8. In the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.

9. In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.

No Contradiction Between Physics And Religion: Max Planck

Max Planck was a German theoretical physicist who is regarded as the father of quantum mechanics. Planck won the Nobel Prize in physics in 1918, for the discovery of energy quanta.

While solving for energy quantum, Max Planck stumbled upon a very small number which is the foundation of modern physics. Planck is well known for this constant which has been named in his honor, h = 6.62607015 × 10-34 m2 kg / s.

Planck came from a traditional family, a generation of theology professors in Gottingen. Plank's father broke that tradition by teaching law. Later on Planck too, as he became a professor of physics. However, while Planck was driven mainly by science, he was also religious by heart.

According to Planck, there was no contradiction between science and religion. Religion and natural science (read: physics) do not exclude each other, as many contemporaries of ours would believe or fear, Planck said. They mutually supplement and condition each other.

The following quotes are by Planck on science and religion:

1. Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve.

2. Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination.

3. My research on the atom has shown me that there is no such thing as matter in itself. What we perceive as matter is merely the manifestation of a force that causes the subatomic particles to oscillate and holds them together in the tiniest solar system of the universe

4. Natural science wants man to learn, religion wants him to act.

5. Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: Ye must have faith. It is a quality which the scientist cannot dispense with.

10 Motivational Quotes By Albert Einstein

Everyone would agree that Albert Einstein was the greatest physicist of all time. Einstein won the Nobel Prize for explaining the photoelectric effect thereby paving a way for quantum mechanics to bloom, but he is most well know for equation E = m c^2.

More than that, Einstein developed a new theory of universal gravitation, an improvement over Newton's version, in which Einstein imagined a curving space and time resulting in a force we call gravity. Einstein spent his last years to find the ultimate theory of the universe.

Today, Albert Einstein is remembered not only as a great scientist, but also as a wise man, who inspired students with his witty remarks. Einstein was featured in the movie Oppenheimer, giving advice to physicist Robert Oppenheimer.

Following are ten quotes by Einstein to help students succeed in academics and in life:

1. Great spirits have always encountered violent opposition from mediocre minds.

2. Never memorize something that you can look up.

3. Anyone who has never made a mistake has never tried anything new.

4. Logic will get you from A to Z; imagination will get you everywhere.

5. The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

6. I have no special talents. I am only passionately curious. The important thing is not to stop questioning. Curiosity has its own reason for existence.

7. The measure of intelligence is the ability to adapt to change.

8. What is right is not always popular and what is popular is not always right.

9. Life is like riding a bicycle. To keep your balance, you must keep moving.

10. I speak to everyone in the same way, whether he is the garbage man or the president of the university.

Physicist Who Coined Black hole & Wormhole

John Wheeler is best known as a physicist who popularized the term black hole. He was called the hero of black hole story by Stephen Hawking. Wheeler also coined the word wormhole for a hypothetical pathway connecting two remote points in space-time.

Wheeler [1911 – 2008] earned his doctorate degree when he was only 21 years old. He worked with such renowned scientists as Niels Bohr and Edward Teller. For most his life, Wheeler was a professor, his most notable student being Nobel laureate Richard Feynman.

Following are 5 brilliant quotes by John Wheeler:

1. Space tells matter how to move. Matter tells space how to curve. This is how Wheeler summarized Einstein's general relativity in one line.

2. The best way to learn something is to have to teach it. said in 1996

3. We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance. to Scientific American, 1992

4. In any field find the strangest thing and then explore it. quoted by James Gleick

5. The universe gives birth to consciousness, and consciousness gives meaning to the universe.

John Wheeler and Richard Feynman

Wheeler joined Princeton University as a professor of physics in 1938, remaining until 1976. Wheeler supervised 46 PhD students at Princeton, more than any other professor. His most notable student was Richard Feynman.

Over the course of time, Wheeler and Feynman developed a friendship and mutual admiration. Feynman referred to Wheeler as his "spiritual father," and they maintained a lifelong connection, even after Feynman moved to Caltech.

Death and legacy

On April 13, 2008, Wheeler died of pneumonia at the age of 96. He is remembered as one of the greatest American physicists of the 20th century. After his death, the University of Texas named the John Wheeler Lecture Hall in his honor.

5 Amazing Quotes By Max Planck On Science

Max Planck [1858-1947] was a German physicist who discovered energy quanta and laid the foundations of quantum mechanics in 1900. This won him the Nobel Prize in physics in 1918.

Best known for Planck's constant, denoted by h, Planck was a devout man who believed that his work with subatomic particles revealed to him the deepest secret of the universe.

According to Max Planck, the very greatest scientists of all times - such as Kepler, Newton, Leibniz - were permeated by a most profound religious attitude.

Early life

Max Planck was the sixth child in a family of intellectuals. His teacher Hermann Muller recognized the young talent and taught Planck astronomy and mathematics early on, aged 12.

Planck was gifted when it came to music. He played piano, organ and cello, and composed songs of his own. However, instead of music he chose physics for a career.

Planck's professor at University of Munich advised him not to study physics because in that field "almost everything is already discovered." Planck replied he just wanted to know more about the universe.

However, by discovering quantum theory Max Planck opened a whole new field of quantum mechanics which in turn gave rise to modern technology.

Quotes by Planck

1. Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination.

2. Science cannot solve the ultimate mystery of nature. That is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve.

3. We have no right to assume that any physical laws exist, or if they have existed up to now, that they will continue to exist in a similar manner in the future.

4. What we perceive as matter is merely the manifestation of a force that causes the subatomic particles to oscillate and holds them together in the tiniest solar system of the universe.

5. Over the entrance to the gates of the temple of science are written the words: Ye must have faith. It is a quality which the scientist cannot dispense with.

5 Motivational Quotes By Madame Curie

Marie Curie (1867-1934) is the only person in history who has won two Nobel Prizes in two different sciences, physics and chemistry. Curie was prohibited from higher education in her native country Poland. She overcame all obstacles and became a leading figure in the academia.

Following are five inspiring quotes by Madame Curie:

Advice to her daughters

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

To make a better world

You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.

Science has great beauty

A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery also has its beauty.

The way to success

I was taught that the way of progress was neither swift nor easy.

Be humble

I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory.

Marie Curie got married to Pierre Curie, along with whom she won her first Nobel Prize in physics. The couple went on a bicycle tour of the French countryside for their honeymoon.

5 Quotes By CV Raman, India's Nobel Laureate

CV Raman was an Indian physicist who won the Nobel Prize in 1930. His discovery of the "Raman Effect" has extensive use in chemistry to provide a structural fingerprint by which strange molecules can be identified. Raman used to say "Ask the right questions, and nature will open the doors to her secrets."

Raman was born into an orthodox South Indian Brahmin family but his interests in the sciences kept him away from religious or spiritual activities. Eventually he described himself as an agnostic. Following are some amazing quotes by the first Indian Nobel laureate in science, CV Raman:

1. There is no Heaven, no Swarga, no Hell, no rebirth, no reincarnation and no immortality. The only thing that is true is that a man is born, he lives and he dies. Therefore, he should live his life properly. (1934)

Many started referring to Raman as an atheist, which he denied.

2. If there is a God we must look for him in the Universe. If he is not there, he is not worth looking for. I am being looked upon in various quarters as an atheist, but I am not. The growing discoveries in the science of astronomy and physics seem to be further and further revelations of God. (1945)

3. In a conversation with Mahatma Gandhi, Raman said "Mahatma ji, religions cannot unite. Science offers the best opportunity for a complete fellowship. All men of Science are brothers."

Raman was also active politically. He was famous for being an advocate of women's rights.

4. I have a feeling that if the women of India take to science and interest themselves in the progress and advance of science as well, they will achieve what even men have failed to do. Women have one quality--the quality of devotion. It is one of the most important passports to success in science.

5. As a political activist, Raman said: It seems to me that the real danger before our country is the crushing down of individual freedom and initiative by the steamroller of government authority. Democracy without freedom for the individual is a sham and a delusion. (1954 interview)

You can judge that CV Raman was not only a pioneering scientist but also a great thinker whose thoughts were progressive and way ahead of the time. Raman was the first Indian to win Nobel Prize in science who contributed immensely to the idea of agnosticism.

5 Spiritual Quotes By Erwin Schrödinger

Austrian physicist Erwin Schrödinger (1887-1961) is well known as one of the founders of quantum mechanics. Schrödinger's equation is to quantum physics what Newton's laws are to classical physics. For his pioneering work, Schrödinger won the Nobel Prize in 1933.

But there is more to Schrödinger than you know. In addition to contributions to physics, Schrödinger is equally famous for being closer to spirituality than any other contemporary scientist. He took particular inspiration from eastern philosophies, such as from India.

Following are five quotes by physicist Erwin Schrödinger on philosophy and spirituality that may be worth your time:

1. We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our bodies belong to it. Not only my own body, but those of my friends, also of my dog and cat and horse, and of all the other people and animals. And this is my only means of communicating with them.

2. The stages of human development are to strive for:

(a) Besitz [Possession]

(b) Wissen [Knowledge]

(c) Können [Ability]

(d) Sein [Being]

The goal of man is to preserve his Karma and to develop it further... when man dies his Karma lives and creates for itself another carrier. [from writings in 1918]

3. This life of yours which you are living is not merely a piece of this entire existence, but in a certain sense the whole. This, as we know, is what the Brahmins express in that sacred, mystic formula which is yet really so simple and so clear; tat tvam asi, this is you. Or, again, in such words as "I am in the east and the west, I am above and below, I am this entire world." [from My View of the World 1951]

4. I am born into an environment — I know not whence I came nor whither I go nor who I am. This is my situation as yours, every single one of you. That is why we are eager to find out about it as much as we can.

And that is science, learning, knowledge; it is the true source of every spiritual endeavor of man. We try to find out as much as we can about the spatial and temporal surroundings of the place in which we find ourselves put by birth…

Although Schrodinger rejected traditional religious beliefs - Jewish, Christian, and Islamic - but he loved to indulge in religious expressions and metaphors. Schrodinger, like Heisenberg was deeply inspired by Vedantic concepts that helped him cope with the absurdity of quantum mechanics.

5. I think that life may be the result of an accident, but I do not think that of consciousness. Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else. (1931)

10 Albert Einstein Quotes To Inspire Students

Albert Einstein was not only one of the greatest physicists of all time, but also famous for his words of wisdom. Students often approached Einstein with their problems and he would be more than willing to help.

The following are just a few of Einstein's wise sayings that will encourage and inspire you to be all that you can be.

1. Do not worry about your difficulties in Mathematics. I can assure you mine are still greater. (In a letter to high school student Barbara Lee Wilson in 1943).

2. I do not carry such information in my mind since it is readily available in books. (In response to not knowing the speed of sound).

Einstein also similarly said, "The value of a college education is not the learning of many facts but the training of the mind to think".

3. Life is like riding a bicycle. To keep your balance you must keep moving. Einstein wrote this gem of an advice in a letter to his son - Eduard, dated 5 February 1930.

4. If A is success in life, then A = x + y + z. Work is x, play is y and z is keeping your mouth shut. (Said to Samuel J Woolf in 1929).

5. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world. (1929)

Einstein's imagination led him to discover new theories in physics. For example, once when he was sitting in his office, Einstein thought: If a person falls freely, he will not feel his own weight. This thought pushed Einstein to a new theory of gravitation.

6. Everyone sits in the prison of his own ideas; he must burst it open, and that in his youth, and so try to test his ideas on reality.

7. I have only two rules which I regard as principles of conduct. The first is: Have no rules. The second is: Be independent of the opinion of others. 1930

8. Never lose a holy curiosity. It is enough if one tries merely to comprehend a little bit of mystery each day. Don't stop to marvel.

9. Try not to become a man of success. Rather become a man of value.

10. I never think of the future. It comes soon enough.

Clearly, Nobel prize winning scientist Albert Einstein had a knack for solving problems - be it in physics or in life in general. He continues to inspire millions of people every day.

Five Quotes By Freeman Dyson On Religion

Freeman Dyson (1923-2020) was no ordinary physicist. In a letter of recommendation to Robert Oppenheimer, Nobel laureate Hans Bethe wrote in praise of Dyson: "He is the best student I have ever had or observed."

Dyson was unusual in that he won the Templeton Prize in 2000, which is given annually in the field of spirituality, recognizing achievements at the intersection of science and religion. Dyson was pleasantly surprised by this honor.

Yes, Dyson was openly religious.

But his God was a kind of meta-scientific, collective consciousness. As someone who regarded the universe as a manifestation of God, Dyson said: The many accidents of physics and astronomy that have worked together to our benefit, it almost seems as if the Universe must in some sense have known that we were coming.

Dyson partially disagreed with fellow physicist Steven Weinberg's view that "with or without religion, good people can behave well and bad people can do evil; but for good people to do evil – that takes religion" and added: "For bad people to do good things – that also takes religion."

Following are 5 quotes by Freeman Dyson on science, religion and life:

1. Both as a scientist and as a religious person, I am accustomed to living with uncertainty. Science is exciting because it is full of unsolved mysteries, and religion is exciting for the same reason. The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe.

2. To talk about the end of science is just as foolish as to talk about the end of religion. Science and religion are both still close to their beginnings, with no ends in sight. Science and religion are both destined to grow and change in the millennia that lie ahead of us, perhaps solving some old mysteries, certainly discovering new mysteries of which we yet have no inkling.

3. Science and religion are two windows that people look through, trying to understand the big universe outside, trying to understand why we are here. The two windows give different views, but they look out at the same universe. Both views are one-sided, neither is complete.

4. Without discipline there can be no greatness. Without diversity there can be no freedom. Greatness for the enterprise, freedom for the individual — these are the two themes, contrasting but not incompatible, that make up the history of science and the history of religion.

5. Over periods of 10,000 years the distinctions between Western and Eastern and African cultures lose all meaning. Over a time span of 100,000 years we are all Africans. And over a time span of 300 million years we are all amphibians, waddling uncertainly out of dried-up ponds onto the alien and hostile land.

As a scientist, Dyson made several important contributions to the field of astrophysics that also bear his name, including concepts like Dyson tree and Dyson eternal intelligence, which find repetitive use in the realm of science fiction.

Dyson was Professor Emeritus in the Institute for Advanced Study in Princeton, remembered by friends and colleagues as shy and polite, with a refreshing view of the world. Physicist Geoffrey Ingram Taylor described Dyson as "the best mathematician in England."

Five Quotes By Stephen Hawking On Religion

Stephen Hawking was one of the most brilliant minds of the 20th century who made fundamental contributions to the theory of black holes. Hawking is well known to the general public by his record-breaking book A brief history of time, which sold over 25 million copies.

Hawking (1942–2018) was given just a few years to live in his twenties, as he was struck by the paralyzing motor neuron disease in 1963. Not only did he beat the odds, but also revolutionized physics for next half a century.

When Hawking ended his bestselling book with the sentence: If we discover the theory of everything... it would be the ultimate triumph of human reason, for then we would know the mind of God, he raised quite a few eyebrows. Hawking later explained that he had used the word "God" figuratively.

On numerous occasions, Hawking had commented that even if God were to be real, he would be bound by the rules of physics. Therefore, is the idea of an all powerful creator even necessary, Hawking wondered often.

For example, Hawking told New Scientist in 2007: (1) I'm not religious in the normal sense. I believe that the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.

In 2011, Hawking would go on to say: (2) We are each free to believe what we want and it is my view that the simplest explanation is there is no God. There is probably no heaven, and no afterlife either. We have this one life to appreciate the grand design of the universe, and for that, I am extremely grateful.

And it is true that Hawking lived life to the fullest. His life threatening disease did not hinder his goals and aspirations. Hawking said, I believe that disabled people should concentrate on things that their handicap doesn’t prevent them from doing and not regret those they can’t do.

In an interview to The Guardian, Hawking remarked on the question of death: (3) I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers. That is a fairy story for people afraid of the dark.

On the question of creation, Hawking is clear: (4) Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.

It may be a coincidence but Stephen Hawking was born on the same day that Galileo Galilei died in 1642. It was Galileo, the father of modern physics, who laid the foundations of science and religion debate, building upon his inner contradictions as a deeply religious man.

Hawking continued the great legacy more than 300 years later. According to him, there is a fundamental difference between religion, which is based on authority and science, which is based on observation and reason. This is also the view held by such greats as Dirac and Feynman. 

(5) We are just an advanced breed of monkeys—Hawking adds—on a minor planet of a very average star. We are so insignificant that I cannot believe the whole universe exists for our benefit (which is the view that religion has). But we can understand the Universe, and that makes us something very special.

10 Inspiring Quotes From Richard Feynman's Letters

Richard Feynman was a Nobel Prize winning American physicist whose letters have grabbed the attention of media far and wide. They included jokes, anecdotes, puzzles and news for his parents while he worked at institutions across America.

The following 10 quotes by Richard Feynman are extracted from the book titled, Don't you have time to think? edited by his daughter Michelle Feynman. The book, published in April 2005, is a unique collection of Feynman's letters.

1) Letter to mom Lucille Feynman, Oct 1939: Professor Wheeler was called away suddenly last night so I took over his course in mechanics for the day. I spent all last night preparing. It went very nicely and smoothly. It was a good experience - I guess someday I will do a lot of that.

Physicist John Wheeler was Feynman's doctoral advisor. This was probably Feynman's first lecture he gave in the absence of Prof Wheeler, as mentioned. He seems to have enjoyed teaching and wanted to share that feeling with his mother.

2) Tell pop I have made out a time schedule so as to efficiently distribute my time and will follow it quite closely. There are many hours when I haven't marked down just what to do but I do what I feel is most necessary then or what I am most interested in.

Like most students Feynman also struggled to manage time. At the time this was written Feynman was quite early in his twenties. As suggested by his father, Feynman made a time table to achieve maximum level of productivity in a day.

3) 1940: I am listening to a course in physiology, study of life processes, in the biology dept. It is a graduate course. I don't know at all as much as the 3 other fellows in the class but I can understand and follow everything easily.

Just like this, Feynman was led to new adventures in life by his curiosity. In a 1979 interview given to Omni magazine Feynman said: I don't know anything, but I do know that everything is interesting if you go into it deeply enough.

4) Letter to Arline, the love of his life, year 1945: I feel I am a reservoir for your strength. Without you, I would be empty and weak, like I was before I knew you... but your moments of strength make me strong and thus I am able to comfort you with your own strength when you are down.

5) Study hard what interests you the most in the most undisciplined, irreverent and original manner possible. Letter to J. M. Szabados (November 1965)

6) Letter to Koichi Mano, February 1966: You say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office.

You are not nameless to me. Do not remain nameless to yourself — it is too sad a way to be. Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.

7) Do not read so much, look about you and think of what you see there. Letter to Ashok Arora, January 1967.

8) The real question of government versus private enterprise is argued on too philosophical and abstract a basis. Theoretically, planning may be good. But nobody has ever figured out the cause of government stupidity — and until they do (and find the cure), all ideal plans will fall into quicksand. 1963 letter to his wife, Gweneth.

9) Tell your son to stop trying to fill your head with science — for to fill your heart with love is enough! Note to the mother of Marcus Chown.

10) Last letter to Arline, written in 1946, after her untimely death due to prolonged tuberculosis: I adore you sweetheart. I find it hard to understand in my mind what it means to love you after you are dead. But I still want to comfort and take care of you — and I want you to love me and care for me.

I want to have problems to discuss with you — I want to do little projects with you. My darling wife, I do adore you. You, dead, are so much better than anyone else alive. I love my wife. My wife is dead. PS: Please excuse my not mailing this but I don't know your new address.
