yall ever heard about the wave
I made this to put on my wall for revision, but I thought it might be helpful for some of you guys too so I thought I would share it!
Superfluid Helium
It was previously thought that superfluid Helium would flow continuously without losing kinetic energy. Mathematicians at Newcastle University demonstrated that this is only the case on a surface completely smooth down to the scale of nanometers; and no surface is that smooth.
When a regular fluid like water is passing over a surface, friction creates a boundary layer that ‘sticks’ to surfaces. Just like a regular fluid, when superfluid Helium passes over a rough surface there is a boundary layer created. However the cause is very different. As superfluid Helium flows past a rough surface, mini tornados are created which tangle up and stick together creating a slow-moving boundary layer between the free-moving fluid and the surface. This lack of viscosity is one of the key features that define what a superfluid is and now we know why it still loses kinetic energy when passing over a rough surface.
Now we can use this information to help our efforts on applications of superfluids in precision measurement devices such as gyroscopes (I think this was on the Big Bang theory where they make a gyroscope using superfluid Helium that can maintain angular momentum indefinitely because it would flow across a smooth surface without losing kinetic energy) and as coolants.
I am pretty sure that this cannot be true because I saw an ad from the corn industry that said high fructose corn syrup is good for you…
A range of diseases – from diabetes to cardiovascular disease, and from Alzheimer’s disease to attention deficit hyperactivity disorder – are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that’s common in the Western diet, in a way that could lead to those diseases.
However, the researchers discovered good news as well: An omega-3 fatty acid known as docosahexaenoic acid, or DHA, seems to reverse the harmful changes produced by fructose.
“DHA changes not just one or two genes; it seems to push the entire gene pattern back to normal, which is remarkable,” said Xia Yang, a senior author of the study and a UCLA assistant professor of integrative biology and physiology. “And we can see why it has such a powerful effect.”

Americans get most of their fructose in foods that are sweetened with high-fructose corn syrup, an inexpensive liquid sweetener made from corn starch, and from sweetened drinks, syrups, honey and desserts. The Department of Agriculture estimates that Americans consumed an average of about 27 pounds of high-fructose corn syrup in 2014. Credit: © AlenKadr / Fotolia
Word for tea in most of the world’s languages are all ultimately related, belonging to two groups of terms.
“Tea” itself belongs to one of those groups. It was a borrowing from Dutch thee, in turn from tê, the reading of 茶 in the Amoy dialect of Min Nan. Those languages whose introduction to tea was primaraly from Dutch traders typically use words likewise derived via the Dutch thee. The Polish herbata is also part of this family, though slightly obscured, being a borrowing from the Latin herba thea.
The other major group is represented by the word chai, a more recent borrowing in English. Chai was borrowed from the Hindi cāy, which in turn came from a Chinese dialect with a form similar to Mandarin chá. Languages that use chai-type terms generally were first introduced to tea through overland trade, ultimately to northern China, while those that use tea-type terms were generally introduced to it via sea trade, from Southern China.
Both tê and chá are derived from the same Middle Chinese form, ultimately derived from Proto-Sino-Tibetan *s-la “leaf”.
This week, we’re taking a look at manuscripts having to do with health, medicine, and human physiology specifically focusing on how bodies are displayed in manuscript illuminations or diagrams across different cultures.
LJS 389 shown above, is a 14th century Chinese treatise on the anatomy, physiology, and pathology of blood vessels titled Shi si jing fa hui. The manuscript is made from bamboo paper and the diagrams and kaishu script are written with black ink. Focus on the diagrams of the bodies and stay tuned this week to see not only how the details and forms of these depictions change from culture to culture, but also the mediums with which these manuscripts are created.
The full LJS 389 manuscript filled with more diagrams can be found on Openn: http://openn.library.upenn.edu/Data/0001/html/ljs389.html

*UPDATED* Here is a masterpost of MOOCs (massive open online courses) that are available, archived, or starting soon. Some are short, some are very interactive, some are very in-depth. I think they will help those that like to learn with a teacher or with videos. I checked each link to make sure they are functioning.

Do you any tips about using ms paint?
I think I have few tips
#1Use 500x500 px or bigger canvas size. Any smaller size will make a brush look messy and shit.Here look:
Can you see the difference?? Lineart in 600x600 px is so much smoother
