“When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.” -Albert Einstein

It's no secret that Elon Musk puts a tremendous number of hours into his work.

It is also said, "Newton, Einstein, Tesla, and few other great scientists were putting too much time in search of truth". As if they were enjoying their time, the work they were doing was like fun to them. Similarly, when I study math sometimes I need someone to remind me "It's time to show you're hungry".

It thus seems like our state of mind can change our perception of time, as pointed out in a previous question on this site.

What can make someone so absorbed in their work that they forget about food?

1 Answer 1


Being deeply immersed in a task is called flow. The term was introduced by Mihály Csíkszentmihályi, a hungarian psychologist. Csíkszentmihályi spent decades on researching this phenomenon and I can highly recommend reading his book: Flow - The Psychology of Optimal Experience
