  1. Today I Learned

    Today I learned, in terms of true depth, the Kola Superdeep Borehole is the deepest borehole in the world. It is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The goal was to to drill as deep as possible into the Earth's crust.
  2. science is subfield of philosophy

    I know science is not a subfield atm but it should be.
  3. I love you

      Get a room, you two.

  4. the Ewald–Oseen extinction theorem

    I never said scattering=refraction. you talk with your faith, it doesn't matter what I say.
  5. the Ewald–Oseen extinction theorem

    Many people call it scattering, especially the ones that know of the extinction theorem. Have a look on google. I think It's rather interaction with atomic electrons. and electrons. Rayleigh and compton scattering are both about the interaction of photons with particles. Their is a feyman diagram that shows this. The fact that scattering implies a change in direction doesn't mean this change in direction is measurable/observable. I have done what I could but I knew only about the theorem when the thread got closed and I got another warning point.. Refraction is the change in direction of wave propagation due to a change in its transmission medium. So for example when light enters an ocean, the first watermolecules the light interact with, cause the refraction. When you take a vacuum as medium then al particles are localized non uniformities. Most of what I said is a copy-paste from the Wikipediapage about the theorem.
  6. replace chemotherapy

    Small interfering RNAs (siRNAs) responsible for brain damage in Huntington’s patients are also toxic to cancer cells, according to researchers at Northwestern University. The findings, published yesterday (February 12) in EMBO Reports, could provide a novel approach to cancer therapy. The siRNAs found in Huntington’s kill cancer cells by targeting genes with complementary TNRs. Using the molecules, Murmann and her colleagues were able to induce cell death in human and mouse ovarian, breast, prostate, liver, brain, lung, skin, and colon cancer cell lines. They also slowed tumor growth in mice with human ovarian cancer, with no toxicity to normal tissues. I find this extremely hopeful.
  7. Today I Learned

    Today I learned an Astronomical Unit (AU) is the average distance between Earth and the Sun, which is about 93 million miles or 150 million kilometers. Astronomical units are usually used to measure distances within our Solar System. For example, the planet Mercury is about 1/3 of an AU from the sun, while the farthest planet, Pluto, is about 40 AU from the sun (that's 40 times as far away from the Sun as Earth is).
  8. Scientists probing the reason why cancer is far less common in individuals with Huntington's disease have revealed that the gene responsible for the fatal brain condition produces a molecule that is deadly to cancer cells.
  9. the Ewald–Oseen extinction theorem

    No, scattering can cause refraction. Your read but you don't understand. When light traveling in vacuum enters a transparent medium like glass, the light slows down, as described by the index of refraction. Although this fact is famous and familiar, it is actually quite strange and surprising when you think about it microscopically. After all, according to the superposition principle, the light in the glass is a superposition of: The original light wave, and The light waves emitted by each of the atoms in the glass. (Remember, light has an electric field that pushes atoms back and forth, which causes the atoms to emit dipole radiation.) Individually, each of these waves travels at the speed of light in vacuum, not at the (slower) speed of light in glass. Yet when the waves are added up, they surprisingly create only a wave that travels at the slower speed. The Ewald–Oseen extinction theorem says that the light emitted by the atoms has a component traveling at the speed of light in vacuum, which exactly cancels out ("extinguishes") the original light wave. Additionally, the light emitted by the atoms has a component which looks like a wave traveling at the slower speed of light in glass. Altogether, the only wave in the glass is the slow wave, consistent with what we expect from basic optics. ->When light traveling in vacuum enters a transparent medium like glass. The photons interact with atoms/electrons (depending on the material the glass is made of). The interaction electron/atoms - photons causes the refraction and is called scattering. Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pas. In glass, the 'glassmolecules' scatter the photons.
  10. true, things I learned concerning entanglement I found amazing
  11. science is subfield of philosophy

    I'm sorry I keep reacting but you people denied science. You people believe the properties of light can change without it's photons that interact with particles. It had nothing to do with a semantic problem. Scattering causes refraction!!!!–Oseen_extinction_theorem Did you even read the theorem? An important part of optical physics theory is starting with microscopic physics—the behavior of atoms and electrons—and using it to derive the familiar, macroscopic, laws of optics. Shell's law is a macroscopic law. OK, I didn't know that. OK, thx for the wisdom. Since all words have definitions, I meant "it's not exactly defined." Empirical science is exact defined, philosophy is not. Philosophy is a more general term then empirical science. Science should be described as a subfield. 1 Special relativity is better described as a philosophical theory. 2 All sciences need philosophy 3 Much has been written on the Demarcation problem, and the difficulties of cosmology are always front and center. But so are the difficulties of many other sciences, including archaeology and astronomy, where you have to take what the universe gives you rather than being able to conduct experiments at will. 4 Problem-solving is an important field of study and discipline in philosophy. Science develops/evolves via problem needs philosophy.
  12. You are not alone. I got 3 downvotes on stuff I said 13 months ago.
  13. Is the Universe infinite?

    OK, but it remains mathematical. Why is there no boundary?
  14. Is the Universe infinite?

    True infinity is like true randomness, it can never be 'proven'. Infinity does not refer to size but to the absence of boundaries.
