Anthropic Principle in Cosmology
The essence of Anthropic principle in single sentence: “The Universe is planned in such a way to admit the existence of a conscious observer who would understand it”. In detail, our universe was “fine-tuned” in ways to make it especially suited to living beings (with or without consciousness). What’s “fine-tuning” – tiny change in any […]

The problem of Free Will is thorny, but it can’t left non-debated. In Newtonian Physics worldview there is no room for Free Will, everything is predetermined. I read a paper of Erwin Schrodinger (one of the greatest physicists of XX century) “Indeterminism and free will” (published in 1936). Quantum Mechanics does not resolve the problem […]

Most archeologists suppose that the reason for lack of civilizations before 12,000 years ago is that unfavorable climate which prevented people from forming civilizations. Homo Sapiens have been around since […]
Hawking Radiation
Stephen Hawking found that quantum fields are disturbed in the proximity of the event horizon of a black hole. Quantum fluctuations in vacuum always produce virtual entangled particle-antiparticle pairs which are quickly annihilated in order to pay the energy back to the Universe (otherwise the law of Energy Conservation is violated, it’s actually violated but […]

Best Lossless Compression Rate of English Text on Average
Number of English letters (incl. capital ones), punctuation symbols is less 128, hence you need 7-bits per English text symbol. The calculated entropy of the English language is 2.62 bits per letter on average. According to Shannon’s Source Coding Theorem the best compression ratio you can obtain without distorting the original text (i.e. by lossless […]
