I love when teachers make things interesting! I asked my chem teacher what this was today (I'm in 10th grade) and she said it wasn't important, and I'd never need to know it for any test and wouldn't explain further. Why can't I just be learning to learn!?!
I’ve heard of Bose-Einstein Condensate but I could never understand it from how they described it in text books. This video actually makes the idea much clearer in my mind, still difficult to imagine but much clearer.
science is just so much more interesting and amazing than just saying "god did it". truly incredible how far we have come and how much more there is to come.
What is really cool is that Michio Kaku in his book Physics of the Impossible says this condensate begins to act like one atom, and might even have the same properties of quantum particles-only visible by the human eye. How cool is that?
There is indeed an experience like this in human understanding. The ego consciousness is our identity. When someone loses their ego/identity, they no longer know who they are nor does it matter.
this doesn't just relate to buddhism as the video description says. it answers questions AND raises even more questions in every single thought and belief
Such state was predicted by Einstein and Bose in 1925. But it was after a freakin' 70 years that it actually made in MIT lab. The coolest thing about BEC is that you can actually SEE the peculiarities of quantum physics. And the even more coolest thing (0K) is that you can actually do teleportation using BECs.
No less strange than the double slit interference pattern. Momentum creates form. Take away momentum and you have nothing but the field of probabilities.
Bose should have won a nobel prize, he always felt he would, but I guess he didn't die an unhappy man because what he discovered was important enough for Einstein to expand on. And thus now, we have 5 states of matter: Plasma, Gas, Liquid, Solid and finally the bose-einstein condensate. :)
I think what he means to say is that the area the atom occupies at lower temperatures is not a single point in space, but a wave in space. The waves aren't movements or vector paths, but a distorted atom shape. Eventually the wave shaped atoms all overlap.
The waves are only meant as purely mathematical instruments that do not exist in physical reality but just in the heads of physicists. They are wave functions which are interpretated as showing the distribution of probability of prensence (or, to be moire precise, of probability density) and eventually overlap (or, as a physicist would say: interfer).
"Taming Gravity" in Popular Mechanics Oct 1999 issue is a good place to start reading up on Dr. Ning Li and her A/C Gravity to see how we're beginning to apply the Bose Einstein Condensate phenomena to technology.
I watched this entire program on PBS about 5 months ago. It was the race to absolute zero, or something along those lines for the title. The Bose-Einstein condensate is a few degrees above absolute 0 if I remember correctly. Super conductivity is pretty cool. It's pretty cool how at such an extremely cold temperature you get a sort of "anti-gravity" effect.
They haven't really figured out any practical applications for it yet. If you watch the Nova video "The Race to Absolute Zero," they do show that it exhibits extremely unusual qualities, such as an ability to flow continuously without the stopping force of friction (it has zero viscosity). They also show a particular one leaking out the bottom of a glass container, as well as defying gravity and climbing up over the side of the container.
Scientists have used Bose Einstein Condensates to literally slow down the speed of light to approx. 38 mph, and were able to turn it off, then start it back up again.
At that point there is no mental distinction from one "person" to another. Once can experience this when they let go of themselves, and become "nobody", because when you are nobody, you can become everybody.
'Have lost my identity - i don't know who i am anymore' on the contrary the atoms become one - returning to the natural state of the whole - the universe is a whole and we are all part of the whole - we are the universe and it is us
Theoretically, can the Bose-Einstein Condensate be cooled so much that the wave-like atoms stretch so far they all together, become one straight line, that doesn't move at all, no matter what you do to it?
Yep, sometimes real systems can be described in terms of a negative temperature on the Kelvin scale, but these systems are way out of equilibrium and undergo a (usually) rapid relaxation to a non-negative temperature. The negative temperature attributed to the initial state is merely a mathematical tool for describing the system out of equilibrium. In systems in equilibrium the temperature on the Kelvin scale is always equal or larger than zero though.
It's like when they get to that certain point. When they cant get closet to each other they break down and become energy to still fit in that space. And when they are heated back up they go back to there former position.
What makes you think I am making a dichotomy between philosophy and science? All I am saying is that we should not have beliefs about the world that are independent of any evidence for (or against) those beliefs. I'm not opposed to abstract ideas or beliefs.
Everything is connected to everything else. If you were large enough, the whole universe would look like a single point. Love thy neighbor as thyself. Treat others how you wish to be treated. Do unto others as you would do have them do to you. The Bose-Einstein Condensate is just science describing the golden rule. Be good to each other. That is the "meaning of life". We're all one.
what seems puzzling is actually universal law. All that exists, detected or undetected is frequency. Matter is various juxtapositions of frequency. What we perceive as different states of matter is a particular juxtaposition of frequency. super cooling the atoms simply reduces them to what they really are- frequency waves- and that's why the condensate can suddenly pass through solid objects. Not unidentified, but simply frequency waves returning to all existing frequency.
In Peter Hamilton's "Reality Dysfunction" when and Edenist dies it transfers their thoughts and personality to a computer w/ whoever elses thoughts are in there, so you can talk to that dead person. However over time it looses is identity and mixes w/ other identities that have been stored for a long time, and they take form of a new identiy. Same thing w/ Bose Condensate! (Did what I wrote make any sense-I wonder?)
@flyingbowser2 Also, superfluids, supersolids, strange matter, fermionic condensates, rydbergh molecules, and quantum hall states. Your mind has just been blown.

2:34 All of this brainy, clever stuff causes me a lot of wonder and confusion too :)
@velomatty 10 months ago nobel prize was given to the team getting a tempretture of 0 kelvin (about 10x10power-7) degree kelvin. and they did realise the formation of bose einstein condensate as einstein has pre explained more than 70 years ago...
No, only certain kinds of atoms called bosons (not related to B part of BEC) make BEC. Theoretically you could use any type of boson, but the two main ones experimented with are Rb and Na, simply because these are the elements that can have lasers made for their wavelengths.
The Bose--Einstein condensate only happens to bosons. The Pauli exclusion principle only applies to fermions. This is actually the reason the phenomenon happens.
the connection of this to Buddhism... there is a term in Buddhism called Ichinen Sanzen which means '3000 realms in a single moment of life' or 3000 different potential states experienced by a person's mind.. calculated .. 10 worlds (or life conditions) x the mutual possession of the 10 worlds x 10 factors (environmental/external factors) x 3 realms of existence = 3000.
My understanding of the wave-particle duality that is shown in the video is that each particle's mass-energy takes on the qualities of a circular standing wave at a frequency proportional to its kinetic energy. This would mean that this condensate would be formed via a quasi joining of the standing waves. Is this the wrong way to go about thinking about it?
wavelength = h / mv get the momentum close to zero and you get the actual atoms to have non-negligible wavelengths. waves interfere with each other. it makes sense.
@tommyXBOX360 She actually does it quite often. She's always contradicting herself and getting answers wrong. Thanks for mentioning the helium fact, I just spent a couple minutes reading over the answer to that! Our world has so many interesting quirks!
Does this have to do with Heisenbergs Uncertaintly principle? I mean, when the atoms stop moving or gets a momentum closer to 0, it's position is getting more uncertain and you get waves of probability of finding the atom instead. These waves then occupies a bigger space the smaller the momentum gets. That would mean that an atom could be anywhere in the universe at absolute 0, perhaps that is why it's impossible to reach absolute 0.
...... and then 70 years ago Bose and Einstein discovered a particle wave could exist in 3000 different positions at once. There are many other points in Buddhism which parallel quantum physics, ie.. entanglement, observer effect, to name a couple.
nope. well, kinda no. the three common states, gas, solid, and liquid (including in between-ish parts like the amorphic liquids like jello or glass), but they all describe the behaviors of molecules depending on energy (heat). With high energy, it goes everywhere, powerful, crazy, like plasma and a beautiful mess of wild, loose atoms and energy, with weird parts when super-heated. When too low (or under high pressure), bose-einstein condensate is the rest of the lower spectrum
@itwasyourfault The laws of thermodynamics state that absolute zero cannot be reached because this would require a thermodynamic system to be fully removed from the rest of the universe.
I agree with you completely in this sense. However, I would argue that even science is subservient to the current worldview. If we see the universe as something to be manipulated and exploited towards egoistic ends (i.e., modernity), then that's how science will be applied. If we believe the universe arises out connectedness and needs to be respected thusly (i.e., Buddhism), then science will be applied entirely differently. At the end of the day, it's still based on dogmatic belief.
@choclate151 I think a few of the related concepts are - Anatta, Indra's net, Sunyata, Dependent origination etc. If you really want to understand look these terms up on wikipedia
Also... You cannot see a BEC with the naked eye, at least you can't tell the difference between a BEC and merely super cold atoms with the naked eye. So in this respect, yes a BEC has been seen, but to actually know if you have one or not you need to look at density measurements.
