On 20th September 1842 Sir James Dewar was born.

This is a bit of a sore one for Dewar and us Scots as James is aknowdeged universally for his invention of the vacuum flask, but never thought to patent it.

James Dewar was interested in cryogenics, the science of extreme cold and in 1898 he was the first person to make liquid hydrogen, which at the time was the coldest substance ever produced.

Cooling gas to the point where it liquefies was an expensive process and Dewar needed to find a way to prevent very cold liquids evaporating while he worked with them. He built boxes insulated with cork, hay or crumpled newspapers, but none kept the liquids cold enough. Eventually he designed a double-walled glass flask and removed the air from the space between the two walls, creating a vacuum. Liquid put inside the flask stays at the same temperature because there are no air molecules through which heat can transfer.

The Dewar flask design was never patented, but two German men who discovered the commercial use for the product renamed it Thermos and claimed the rights to the commercial product and the trademark to the name so although credited with the invention Dewar made no money out of his invention by rights we should be calling the flask a Dewar rather than a Thermos the name we still use to this day. Dewar lost a court case against Thermos due to him not getting the flask patented.

I hope so u believe in soul unlike AMERICAN DARWIN ASIT AND PHYSISCIST WHO think human body is just a machine ..

Yes productivity is required ... But without crea.....

Mr Murthy it is a good achievement for u,for Indian economy and achievement of AMERICAN CAPITALISM in speedy mechanization of human body

Sorry not it's soul....

Accept this Prazim doodle as I can't draw much this weekend

Was looking at that “You’re not even a good villain” gifset again, and have successfully convinced myself in the second gif he’s saying “Witts...”, likely in a “I love you and I’m trying not to laugh, but you are honestly so stupid sometimes” tone of voice, as he rolls his eyes dramatically at whatever they just said to him

particle physiscist is a tommyinnit stan :/

[sealedbeastnue]

question for physiscist: Cut it out. just stop that

[reddish-green-personality]

you dont have to be a physiscist to say that time is relative

people already new that before Einstein

timezones were made in the 19th century

Hi. I am not normal. *slams head into wall* I’m me.

*pats your head*

issokay

everyone is not normal in some way or the other

and i think that is the only normal thing about us all

It is shameful that there are so few women in science. In China there are many, many women in physics. There is a misconception in America that women scientists are all dowdy spinsters. This is the fault of men. In Chinese society, a woman is valued for what she is, and men encourage her to accomplishments yet she remains eternally feminine.

Graduate position: RoyalHolloway_ULondon.EvolutionGenomicArchitecture

The following PhD studentship is available at Royal Holloway, University of London: The Evolution of genomic architecture It is a 4 year funded PhD that will be part of the London NERC Doctoral Training Programme (see london-nerc-dtp.org/). The studentship is fully funded for 4 years for UK/EU applicants (residence conditions apply). Tuition Fees: £4,195.00 p.a. Stipend: £16,553.00 p.a. with London Weighting. Closing date 8/1/18. For further details how to apply see http://bit.ly/2j3uRvG degrees/phdstudentships2017.aspx We are looking for candidates with an interest in this fundamental biological question, and preferably some modelling experience. This includes biologists with an interest and some experience in modelling as well as mathematicians/computer scientists/physiscists etc with an interest in evolutionary biology For further information contact vincent.jansen@rhul.ac.uk The Evolution of genomic architecture Supervised by profs Vincent Jansen (Royal Holloway) and Nick Lane (UCL) How did life on Earth form? Why are our cells the way they are? These are still open questions. Mitochondria transitioned from free-living bacteria to obligate symbionts of eukaryotic cells. In this process they gave up a good part of their genome (either lost or transferred to the nucleus of their host cell) and their reproductive independence (which is now controlled by the nucleus). Little is known regarding this fundamental transition (explained in detail in Nick Lane's book "The vital question"). What are the selective pressures on genes in the mitochondria and the nucleus? Is there an advantage to being in the mitochondria, where you will be passed on to all daughters, or is it better to be in the nucleus, where you could be passed on to sons and daughters? We are interested in which scenarios favour the transfer of genes from bacteria engulfed by a cell to the nucleus, and the transfer of reproductive control to the host nucleus. We do this through studying models of the evolutionary dynamics of mitochondrial genes, trying to quantify private interest and the common good of genes, building on recent modelling advances (as in Ubeda and Jansen 2017). In this work we will take a gene eye-view on the evolution of mitochondria we will be able to determine when the gene copies in the nuclear genome would outcompete the ones in the mitochondrial genome. In a further stage it might be possible to test model predictions using model organism such as Chlamydomonas and Yeast. Candidates interested in applying for this project will need an interest to work on questions relating to the fundamental principles in the evolution of life. We would be very happy to consider candidates with a background in quantitative sciences, such as mathematics, physics, or computer science. References N. Lane. The Vital Question.

scifi story i will never write but would 100% read or watch:

it is 2600. The Jews left the planet earth 200 years ago. They live on a planet no one knows the location of. They left not because they do not love this world, not because they did not love Eretz Yisroel, but because they saw the writing on the wall. It was time. The children went first, along with the childcare workers and community leaders and experts in religious and cultural history and current practice, then the doctors, the nurses, the CNAs, Lab techs and PCAs, then those with farming experience, etc. They pray towards Earth, though we have no real hope of returning. Our top physiscists figured out how to move our planet 3 seconds forward in time, so the goyim couldn’t find it, after they decided to use our solar system as a dump for their radioactive waste. Because they used our solar system for a dump of their radioactive waste, they have accomplished their ultimate goal: our reproductive potential is compromised. So we create Golems (genetically engineered superior goyische passing soldier/spies) and we create time travel and we send them to rescue the children who were killed in Egypt and under Roman occupation and by Europeans and on and on and on and by the Germans and the Germans and the Germans and the French and Italians and the French and Italians and the Russians and the Russians and the Russians and the United States and so on and on and on and on and on and we bring them forward. we save them and they are our future and it’s messy...

and the golem, who were designed specifically to assimilate and to Not Be Human, acquire humanity through empathy and compassion and become Us, and then. we are not finished. And sometime, sometime the ones who expelled us need our help and I don’t know if we give it to them.

I don’t know if we should.

Next year in Jerusalem, but how can that Be, when those who do not see us as human, those who do and don’t see that as enough, are in charge of our world?

in summary i want a well executed sci fi series about what happens When (not if. it’s no longer if) we leave.
