According to Alcubeirre's metric, by expanding space behind a spacecraft and compressing space in front of it a spacecraft is able to move forward in speeds faster than c. This is similar to surfing on a wave - only that in this case, its a wave caused by distortion of space. T.. Ferromagnetism and Magnets(자석의 원리) Ferromagnetism Ferromagnetic objects are objects that consist of magnetic domains each with magnetic fields, arranged in opposite directions in nature, but alligned when an external magnetic field is applied. All ferromagnetic materials loose their ferromagnetivity when heated over the Curie temperature. Each ferromagnets have different Curie temperatures. Condition of Ferrromagnets All ferromag.. Motor Proteins(모터 단백질) ATP and ATP hydrolysis To understand how motor proteins 'walk' around, one has to know what ATP and ATP hydorlysis is. ATP is a battery-like molecule, standard to every living organism. the phosphoanhydirde bonds between every phosphorus and an oxygen atom to its right has a high potential energy, or 'stored energy'. This energy is used to power countless actions in an organism. Hydrolysis is ho.. Matrices - the basics 보호되어 있는 글입니다. Helmholtz Resonator - how blowing bottles creates sound(페트병 불기의 원리) When you blow the top of a bottle, it usually makes a wind instrument-like sound. The pitch seems to be higher when there's less water in the bottle. How is this sound made? The answer is: helmholtz resonance. When wind is blown to the top of the bottle's neck, it can be thought that air in the part of the bottle's neck resonates up and down. Since this is the only movement of air in the bottle(.. How red eyes are caused - the science behind it(눈 충혈이 일어나는 이유) Red eyes(bloodshot eyes) happen by various reasons - from allergies to even exposure to sunlight. A list of these causes are: allergies dry air/dust too much exposure to sunlight gas substance in the air (gasoline, etc) chemical substances smoke/flue gas All of these can be harmful to your eyes and cause inflammation. In order to prevent or stop inflamation, your body causes vasodilation of bloo.. Why lightning strikes the highest places(번개가 잘 떨어지는 곳) Lightning strikes have been a mystery to mankind since the appearance of thought. In the long past, people were afraid of it, and imagined it as a weapon of Zeus. We are still unearthing the mysteries of lightning, and there are still a few unsolved ones, but that's not the point. One of the most interesting facts about lightning strikes is that they seem to hit only high places. Then how come l.. Pattern of palindromes(팔린드롬의 규칙) A week ago I was just listing binary numbers, to see if there's any pattern in them(cause it's fun to do!). After I while, I noticed that there were the same number of palindromes in 1-digit and 2-digit numbers , another number of palindromes in 3-digit and 4-digit numbers, and so on. Palindromes are numbers that have the same digits starting from the front and the back. In other words, the left.. 이전 1 2 3 4 5 6 다음
