 Summary of Human Evolution

ABOUT 13.5 BILLION YEARS AGO, MATTER, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry. About 3.8 billion years ago, on a planet called Earth, certain molecules combi...

 Evolutionary History Through Macro and Micro Observations

Everything in the cosmos has a history. The old dichotomy between the "historical" sciences (like geology, paleontology and evolutionary biology) and the (for want of a better term) "functional" sciences (like physics and chemistry—some would call them the "real sciences") was always supposed to be that fields like physics study dynamic processes and discover immutable laws of interaction among particles composing the cosmos—while the historical sciences study, well, history—the suppose...

 Unlike Physics, Biology Can't Ignore Information

Physicists love to think about systems that take only a little information to describe. So when they get a system that takes a lot of information to describe, they use a trick called 'statistical mechanics', where you try to ignore most of this information and focus on a few especially important variables. For example, if you hand a physicist a box of gas, they'll try to avoid thinking about the state of each atom, and instead focus on a few macroscopic quantities like the volume and total en...

 Kai Krause: The Uncertainty Principle

Heisenberg’s idea had quickly been dubbed Unschärferelation, which transliterates to “unsharpness relationship,” but as there is really no such term in English ('blurred', 'fuzzy', 'vague' or 'ambiguous' have all been tried), the translation ended up as "the Uncertainty Principle"—when he had not used either term at all (some point to Eddington). And what followed is really quite close to the analogy as well: rather than stating that either position or momentum are "as yet undetermin...

 Foundation and Empire

"Well," Bayta's eyes misted with thought as she curled her bare toes into the white softness of the rug and nestled her little chin in one plump hand, "it seems to me that the whole essence of Seldon's plan was to create a world better than the ancient one of the Galactic Empire. It was failing apart, that world, three centuries ago, when Seldon first established the Foundation – and if history speaks truly, it was falling apart of the triple disease of inertia, despotism, and maldistributi...

 Intellectual Exploration as Geographical Exploration

My own field of physics is passing today through a phase of exuberant freedom, a phase of passionate prodigality. Sometimes as I listen to the conversation of my young colleagues at Princeton, I feel as if I am lost in a rain forest, with insects and birds and flowers growing all around me in intricate profusion, growing too abundantly for my sixty-year-old brain to comprehend. But the young people are at home in the rain forest and walk confidently along trails which to me are almost invisib...

 The Mistake of Not Taking Theories Seriously Enough

This is often the way it is in physics. Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough. It is always hard to realize that these numbers and equations we play with at our desks have something to do with the real world. Even worse, there often seems to be a general agreement that certain phenomena are just not fit subjects for respectable theoretical and experimental effort. . . . The most important thing accomplished by the discovery o...

 When Politics Gives Way to Physics

People who take pride in the same object can form a knightly order but not a brotherhood of loving sons. However, as soon as pride in the exploits of the fathers is replaced by grief over their death, we will begin to perceive the Earth as a graveyard and nature as a death-bearing force. Then politics will yield to physics, which cannot be separated from astronomy. Then the Earth will be seen as a heavenly body and the stars as so many earths. The convergence of all sciences in astronomy is a...

The "object" here is pride in culture, nations, and states. The "resurrected generations" refers to the transhuman belief that we will resurrect our dead to join us one day.

 Blurred Boundaries in the Sciences

Science is taking on a new aspect which is neither purely physical nor purely biological. It is becoming the study of organisms. Biology is the Study of the larger organisms; whereas physics is the study of the smaller organisms.

 Example of How Language Affects Thought

Another way of describing the revolution in physics is to say that the key moves and acts, physicists do not care; 'matter' to them means 'to matter'. moves and acts, physicists do not care; 'matter' to them means 'to matter', to make a difference. But our language is still geared to express 'states of being', rather than processes. In this connection, also, the German language helps to explain German philosophy. The Germans have been especially prone to hypostatize their abstractions, identi...
