Einstein’s Cosmos,
Często się twierdzi, że ze wszystkich teorii powstałych w tym stuleciu najgłupsza jest teoria kwantowa. Niektórzy uważają, że na jej korzyść przemawia wyłącznie to, iż jest niepodważalnie poprawna.
In the future, I can imagine that we will genetically modify ourselves using the genes that have doubled our life span since we were chimpanzees.
Democracies are slow to anger and hesitant to go to war: Voters don't want to sacrifice their children for the glory of a selfish king.
In the 1950s, we had all these B-grade science-fiction movies. The point was to scare the public and get them to buy popcorn. No attempt was made to create movies that were somewhat inherent to the tr...
I like to engage the public because when I was in high school, I had all these questions about anti-matter, higher dimensions and time travel. Every time I went to the library, every time I asked peop...
I have concluded that we are in a world made by rules created by an intelligence.
I'm a physicist, and we have something called Moore's Law, which says computer power doubles every 18 months. So every Christmas, we more or less assume that our toys and appliances are more or less t...
El tiempo se frena más dentro de un cohete cuanto más rápido se mueve.
Men imagine gods to be born, and to have clothes and voices and shapes like theirs....Yea, the gods of the Ethiopians are black and flat-nosed, and the gods of the Thracians are red-haired and blue-ey...
El reconocimiento de patrones, como ya hemos visto, es uno de los principales obstáculos para la inteligencia artificial.
Cualquier imagen tridimensional contiene una enorme cantidad de información: un montón de veces la información almacenada en una imagen bidimensional.
Before an observation is made, an object exists in all possible states simultaneously. To determine which state the object is in, we have to make an observation, which collapses the wave function, and...
A stable wormhole is therefore a balancing act, and the key is to maintain the right mixture of positive and negative energy. You need lots of positive energy to naturally create the gateway between u...
No one knows when a robot will approach human intelligence, but I suspect it will be late in the 21st century. Will they be dangerous? Possibly. So I suggest we put a chip in their brain to shut them...
I believe that science is the engine of prosperity, that if you look around at the wealth of civilization today, it's the wealth that comes from science.
Such thinking is sheer speculation, but the laws of physics allow for the possibility of opening a hole in space by concentrating enough energy at a single point, until we access the space-time foam a...
String theory, therefore, is rich enough to explain all the fundamental laws of nature. Starting from a simple theory of a vibrating string, one can extract the theory of Einstein, Kaluza-Klein theory...
Roughly speaking, the greater the value of the metric tensor, the greater the crumpling of the sheet. No mattet how crumpled the sheet of paper, the metric tensor gives us a simple means of measuring...
In sum, the fruition of 50 years of research, and several hundred million dollars in government funds, has given us the following picture of sub-atomic matter. All matter consists of quarks and lepton...
