'A human being is part of the Universe.. limited in time and space.

He experiences himself.. as something separate, a kind of optical delusion of his consciousness.

The striving to free oneself from this delusion is the one issue of true religion'

'Science makes people reach selflessly for truth and objectivity; it teaches people to accept reality, with wonder and admiration, not to mention the deep awe and joy that the natural order of things brings to the true scientist.'

'My pacifism is an instinctive feeling, a feeling that possesses me because the murder of men is disgusting. My attitude is not derived from any intellectual theory but is based on my deepest antipathy to every kind of cruelty and hatred'

'It is in .. times of evil that men recognize their helplessness and their profound dependence..

In the Bhagavad-Gita it says, "Man is a creature whose substance is faith. What his faith is, he is.."

For this reason it is possible to maintain the hope.'

Beatles and the Butterfly Effect

A little-noticed feature of Paul McCartney's 2018 video 'Who Cares?' is that his character is called 'Dr. Lorenz,' after meteorologist Edward Lorenz, the founder of chaos theory, and refers to chaotic order from disorder:

Albert Einstein and psychologist Sigmund Freud greatly admired each other.

Here is a portrait of Einstein, painted by Ferdinand Schmutzer, that was part of Freud's personal collection.

It is now housed in the Freud Museum, Vienna.

Do multiverses exist? Physics says: Maybe. Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

Nothing can beat learning quantum physics from one of its greatest masters.

The mathematical elegance of Paul Dirac's proofs and explanations truly boggles the mind.

The Horn Antenna in Holmdel, New Jersey

Using that instrument, Arno Penzias and Robert Wilson accidentally discovered the persistent radio hiss that had a profile consistent with relic radiation from the Big Bang, cooled down over billions of years.

One is never too old to master a new creative endeavour.

Wolfgang Amadeus Mozart waited until he was 5 years old until he had the age and experience needed for musical composition.

'I was delighted too when I heard about the Nobel Prize, thinking as you did that my bongo playing was at last recognised. Imagine my chagrin when I realised that there had been some mistake: Β—they cited marks I made on paper 15 years ago and not one word about percussion technique'
