The most complex object in the known universe: brain, only uses 20 watts of power. It would require a nuclear power plant to energize a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that's a compliment.
Interpretation
The brain is an incredibly efficient organ that operates on minimal power compared to machines.
This quote highlights the exceptional efficiency and complexity of the human brain, comparing its low power consumption to that of a massive computer. Michio Kaku emphasizes that despite being perceived as 'dim' at times, our brains are remarkably sophisticated and capable, efficiently managing functions with minimal energy—much more so than any artificial system could hope to achieve without immense power.
In practice
During a science talk about the brain's efficiency in energy usage.
The Europeans and the Americans are not throwing $10 billion down this gigantic tube for nothing. We're exploring the very forefront of physics and cosmology with the Large Hadron Collider because we want to have a window on creation, we want to recreate a tiny piece of Genesis to unlock some of the greatest secrets of the universe.
Cancer is like the common cold; there are so many different types. In the future we'll still have cancer, but we'll detect it very, very early, so that it won't kill anybody. We'll zap it at the molecular level decades before it grows into a tumor.
When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.
Consciousness-one level is understanding where we are in space. Consciousness two is where we understand our position in society: who's top dog, who's underdog and who's in the middle. And type-three consciousness is simulating the future. And type-three consciousness, only humans have this ability to see far into the future.
Some advice: keep the flame of curiosity and wonderment alive, even when studying for boring exams. That is the well from which we scientists draw our nourishment and energy. And also, learn the math. Math is the language of nature, so we have to learn this language.
After that cancellation [of the Superconducting Super Collider in Texas, after $2 billion had been spent on it], we physicists learned that we have to sing for our supper. ... The Cold War is over. You can't simply say "Russia!" to Congress, and they whip out their checkbook and say, "How much?" We have to tell the people why this atom-smasher is going to benefit their lives.
Notwithstanding all that has been discovered since Newton's time, his saying that we are little children picking up pretty pebbles on the beach while the whole ocean lies before us unexplored remains substantially as true as ever, and will do so though we shovel up the pebbles by steam shovels and carry them off in carloads.
If the tribal peoples actually represented Western origins at a much earlier time, it was exceedingly valuable that they should be studied intensely for clues about the nature and origin of human society. Consequently it was an injury to science and human knowledge to allow the military to simply exterminate them.
Eureka! Eureka!_x000D_ _x000D_ Supposed to have been his cry, jumping naked from his bath and running in the streets, excited by a discovery about water displacement to solve a problem about the purity of a gold crown.
The voice I use is a very old hardware speech synthesizer made in 1986. I keep it because I have not heard a voice I like better and because I have identified with it.
Science is among the most profoundly human of our activities. Far from being subsumed by the dehumanising effects of technology, science, in fact, remains our last stand against it.
I was a science fiction geek. That lets you know that they come in all sizes and styles, right?
