Extra dimensional theories are sometimes considered science fiction with equations. I think that's a wrong attitude. I think extra dimensions are with us, they are with us to stay, and they entered physics a long time ago. They are not going to go away. Leonard Susskind agoattitudeconsider share on social

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 arbitrarycollectiondiscomfort share on social

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 bronxfamilyfather Change image and share on social
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 audiencecreateexplain share on social
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 businesscollegeengineer share on social
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 biteconfuseconvert share on social
