When your parents are still alive, the material state of Bose-Einstein is unique. In 1995, two scientists Cornell and Wiman eventually made condensate. Consider the way condensation and gas molecules gather and condense into liquid once you hear the word condensation. Molecules become dense or dense

The other two scientists, Satyendra Bose and Albert Einstein, predicted this in the 1920s, but they did not have the facilities and facilities to do it. Now we do. When the plasma is overheated and is excessively excited, the atoms of Bose Einstein condensate (BEC) are completely opposite. They are super excitement and super cool atom.

First let's explain the condensation. Condensation occurs when several gas molecules gather to form a liquid. It all comes from energy loss. Gas is a truly exciting atom. When you lose energy, you start decelerating and collecting. They can collect a drop. When water is boiled, steam (HO) vapor in the form of steam condenses on the lid. It cools the metal and turns into liquid again. Then you will condense

BEC occurs at very low temperatures. I already explained about the temperature scale and temperature. At zero Kelvin (absolute zero), all molecular motion stops. Scientists have found a way to raise the temperature by just a few billionths of absolute zero. Once the temperature goes down, you can create a BEC that contains several special elements. Cornell and Wyman did it with (Rb)

That's why it's very cold. The cold ice is still sturdy. Special things happen when reaching a temperature close to absolute zero. Atoms begin to gather. Since the whole process occurs in the temperature range of billions of degrees, you will not see this at home. At very low temperatures atomic parts can not move at all. They lost almost all energy

Since there is no further energy transfer (like solids or liquids) all atoms have exactly the same level as twins. The result of this aggregation is BEC. The Yuhara son is in the same place and forms a "super atom". Independent atoms are less than 1000 pieces. They all have the same quality and become a group for our purposes

The helium atom gas velocity distribution data (three-sided view) confirms the discovery of a new phase - Bose - Einstein condensate of matter -. Left: Bose-Einstein Just before the condensate appears. Center: Displayed immediately after condensation. Right: After further evaporation, almost pure condensate sample remains. Satyendra Nath Bose first sent Einstein a paper on quantum statistics of photons (now called photons). I came up with Planck's law of quantum radiation without mentioning classical physics. Einstein translated the paper from English to German and submitted it to ZeitschriftfürPhysik (Einstein's manuscript was thought to be lost in 2005). The library of Leiden University was discovered). Einstein then expanded the view of Bose to the important contents of the other two papers.

Bose-Einstein condensate was originally proposed by Satyendra Nath Bose and Albert Einstein between 1924 and 25 years. After 70 years, its existence has been proved. In 1995 Eric Cornell and Carl Wieman made the first Bose-Einstein condensate at the University of Colorado. MIT's Cornell, Wieman, Wolfgang Ketterle received the 2001 Nobel Prize in Physics. Normally, to get enough coolness to condense Bose Einstein, you first need to capture them with a magnet and then take away all the energy by emitting a laser from them. This is not cool enough yet. Some particles will still bounce off in many places, and only some will lie down well. Then slowly decelerate the magnetic field and let out faster bouncing particles. This will leave us the coldest and slowest atoms
