Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there’s no coherent final consensus on why there is space. – Leonard Susskind
I have a funny mental framework when I do physics. I create an imaginary audience in my head to explain things to – it is part of the way I think. For me, teaching and explaining, even to my imaginary audience, is part of the process. – Leonard Susskind
Einstein, in the special theory of relativity, proved that different observers, in different states of motion, see different realities. – Leonard Susskind
I’m afraid I am a bit of a technophobe – a nineteenth-century man caught in the twenty-first century. But there is one piece of technology that I would especially welcome: a device to automatically balance restaurant tables on all four legs so that they don’t rock back and forth. – Leonard Susskind
I often feel a discomfort, a kind of embarrassment, when I explain elementary-particle physics to laypeople. It all seems so arbitrary – the ridiculous collection of fundamental particles, the lack of pattern to their masses. – Leonard Susskind
A lot of my research time is spent daydreaming – telling an imaginary admiring audience of laymen how to understand some difficult scientific idea. – Leonard Susskind
Over the years, I began to understand that there were a lot of people out there reading physics in popular literature that they could not understand – not because it was too advanced, but because it wasn’t advanced enough. – Leonard Susskind
I went to college because my father thought that I should learn engineering, because he wanted to go into the heating business with me. There, I realized I wanted to be a physicist. I had to tell him, which was a somewhat traumatic experience. – Leonard Susskind
I’m a great believer in our ability to come up with the ideas necessary to solve the big questions. I have less confidence that we’ll be able to find a consensus about which ones are right without experiment. – Leonard Susskind
I was from a poor Jewish family in the South Bronx. My father was a plumber, but when I was 16, he got sick and I had to take over. Being a plumber in the South Bronx wasn’t fun. – Leonard Susskind
I did not come from an academic background. My father was a smart man, but he had a fifth-grade education. He and all his friends were plumbers. They were all born around 1905 in great poverty in New York City and had to go to work when they were 12 or 13 years old. – Leonard Susskind
I’m doing physics because I’m curious about how it works – full speed ahead, damn the torpedoes, don’t worry about whether somebody is going to be able to do an experiment next week, just figure it out. – Leonard Susskind
It seems hopelessly improbable that any particular rules accidentally led to the miracle of intelligent life. Nevertheless, this is exactly what most physicists have believed: intelligent life is a purely serendipitous consequence of physical principles that have nothing to do with our own existence. – Leonard Susskind
Man – life in general – seems irrelevant to the workings of the universe: a mere smudge of water, grease, and carbon on a pinpoint planet circling a star of no special consequence. – Leonard Susskind
I’m a great believer that scientists should spend as much time as possible explaining, and you do explain in the process of teaching. – Leonard Susskind
Whether or not evolution is compatible with faith, science and religion represent two extremely different worldviews, which, if they coexist at all, do so most uncomfortably. – Leonard Susskind
Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it’s not tiny? We have no consensus about these things. We’re still exploring them. – Leonard Susskind
Is the universe ‘elegant,’ as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant – if I only knew what they were. – Leonard Susskind
You have to say now that space is something. Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? – Leonard Susskind
The most important single thing about string theory is that it’s a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That’s big news. – Leonard Susskind
Every time a bit of information is erased, we know it doesn’t disappear. It goes out into the environment. It may be horribly scrambled and confused, but it never really gets lost. It’s just converted into a different form. – Leonard Susskind
I have always enjoyed explaining physics. In fact it’s more than just enjoyment: I need to explain physics. – Leonard Susskind
Life is fragile: it thrives only in a narrow range of temperatures between freezing and boiling. How lucky that our planet is just the right distance from the sun: a little farther, and the death of the perpetual Antarctic winter – or worse – would prevail; a little closer, and the surface would truly fry anything that touched it. – Leonard Susskind
Physics is perceived as a lonesome, nerdy kind of enterprise that has very little to do with human feelings and the things that excite people day-to-day about each other. Yet physicists in their own working environment are very social creatures. – Leonard Susskind
