I have been connected with the Niels Bohr Institute since the completion of my university studies, first as a research fellow and, from 1956, as a professor of physics at the University of Copenhagen....
I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.
A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like...
First of all, time travel per se does not exist. 'Travel' implies that you choose both your destination and when you come back. It's more a 'time shot,' a 'time through.' But it's definitely not time...
Planck... and Bohr... have invented systems containing electrons of which the motion produces no effect upon external charges... Not only is this inconsistent with the accepted laws of...
Infinity... is used in physics simply as a shorthand for a very big number.
Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy. Heat, like gravity,...
It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase.
You are exporting disorder {in the form of heat into the Universe} now as you read this book. You are hastening the demise of everything that exists, bringing forward by your very existence the...
So many of the properties of matter, especially when in the gaseous form, can be deduced from the hypothesis that their minute parts are in rapid motion, the velocity increasing with the temperature,...
Noether's theorem fused together symmetries and conservation laws - these two giant pillars of physics are actually nothing but different facets of the same fundamental property.
The infinite zero of a black hole - mass crammed into zero space, curving space infinitely - punches a hole in the smooth rubber sheet. The equations of general relativity cannot deal with the...
It baffled me how people could resist math's gorgeousness, but people did, and people do. The fine of its purity drives them away, the purity of the fine, unmixed with the heaviness of unnecessitated...
Three quarks for Muster Mark!
I'll be looking for you, Will, every moment, every single moment. And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me...
But in the dynamic space of the living Rocket , the double integral has a different meaning. To integrate here is to operate on a rate of change so that time falls away: change is stilled...'Meters...
The Red Lion was a four-ale bar with a handful of lowbrowed sons of toil who looked as though they...
What could you do? Major Major asked himself again. What could you do with a man who looked you...
If I turned towards books, it was because they were the only sanctuary I knew, one I needed in order...
We all had to pay, but not for the crimes we were accused of. There were other scores to settle.
Hope for some means its loss for others; when the hopeless regain some hope, those in power--the...
Why are they going to disappear him? I don't know. It doesn't make sense. It isn't even good...
Keep in mind that when we talk of a great painting we are not really talking about anything great....
It isn't even good grammar. What the hell does it mean when they disappear somebody?
Read me back the last line. 'Read me back the last line,' read back the corporal who could take...
