'How Close Are We To Sending Humans To Mars?' You Should Be Asking 'How Close Are We To Sending Humans Back To The Moon?'
People often ask, "How close are we to sending humans to Mars" and it's not surprising given the optimistic presentations by Elon Musk and others. However, I think this is the wrong question to ask. It is just far too far away to send humans at this stage. What we need to know right now is, “How close are we to sending humans back to the Moon”.
It is of little importance to be able to send the mass of a spaceship with humans to Mars. We could have sent a dead astronaut to Mars decades ago. The challenge is to send a live astronaut there. And that’s much more than sending the mass of the human + food + life support, water etc.
Now, the point of this article is to make sure you can USE the data you are able to get on the web. I use to say "there's not such a thing as too much information", but then I shoud qualify that statement: it all depends on whether you have a brain and a will to put it to work.
My New Encyclopedias Of Astrobiology, Microtonal Music, And Buddhism, Spawned From Wikipedia - Is This The Way Of Its Future?
This originated as my answer to a Quora question: "In what general knowledge domains do alternatives to Wikipedia exist that are significantly superior?". So - I think my own new wikis are, for a simple reason. Because they are based on Wikipedia, but set up to fix things that can’t be fixed in Wikipedia,. It's not hard to improve in topic areas where it has many errors, significant topics are ignored, and its out of date. Sadly, that is happening in many areas of the vast encyclopedia, though much of it is still excellent.
These are my new wikis:
The importance of the detection of single, isolated photons of high energy has risen enormously since then, given their role in the discovery of the Higgs boson. Photon jets are in fact the background to beat down if you want a neat peak of H --> γγ decays to pop out of a mass histogram constructed from events featuring two photon candidates.
The transition from ape-like shuffling to upright walking (bipedalism) as we do has long fascinated scientists. Why did it happen? When?
The second question is a little closer to being solved. An analysis of 3.6 million year old hominin footprints in Tanzania suggests our ancestors evolved the hallmark trait of extended leg, human-like bipedalism substantially earlier than previously thought. Many millions of years before humans. Like the chicken and the egg, there is a clear science answer about which came first even if philosophers are baffled.
Once upon a time we all knew what censorship was, who the good and bad guys were, and what could be done to make the world a better place. Look up the noun “censor” in the Oxford English Dictionary and you’ll find an outline of a much-told story under definition 2 (b):
“An official in some countries whose duty it is to inspect all books, journals, dramatic pieces, etc, before publication, to secure that they shall contain nothing immoral, heretical, or offensive to the government.”
Attributing the first instance of this usage to the English poet John Milton, the lexicographers illustrated it with a quotation from his anti-censorship pamphlet, Areopagitica (1644):
Type 2 diabetes, which unlike Type 1 does not involve an inability to produce insulin but rather involves insulin production being overworked, is overwhelmingly related to obesity. That is why unlike Type 1 it is more of an adult disease. To prevent it requires more than using a type of food, it involves consuming less of all foods.
Where do the Jewish people come from? This is a question that anthropologists, historians and theologists have studied for millennia.
According to mythology, the Judaeans descended from three patriarchs, Abraham, Isaac, and Jacob, who are buried in the Cave of the Patriarchs (Cave of Machpelah) in Hebron – a city in the Palestine region and a world heritage site located in the southern West Bank, 19 miles south of Jerusalem.
The worst effects of the UK’s housing crisis include rising levels of homelessness, and growing numbers of people being housed in unsafe or overcrowded conditions. According to the charity Crisis, 59,890 households were accepted as homeless in England in 2017. And according to recent statistics, 27% of privately rented homes and 13% of homes in the social housing sector are not classed as “decent”.
The Federal Court of Appeal decision that halted construction on the Trans Mountain Pipeline expansion has thrown Canada into a tizzy.
While British Columbia First Nations and environmentalists are celebrating a rare court victory on this project, industry representatives, trade unions and many other First Nations who supported the expansion feel the decision is a nightmarish intervention in plans that were many years in the making.
In recent findings, 5.8 percent of boys and 4.2 percent of girls said they had experienced dating violence in the past year. The good news is that dating violence among teens has declined overall, from 6 percent of teens reporting dating violence in 2003 down to 5 percent in 2013.
The project began with a hemispherical glass dome to show how they could overcome the challenge of printing electronics on a curved surface. Using a custom-built 3D printer, they started with a base ink of silver particles. The dispensed ink stayed in place and dried uniformly instead of running down the curved surface. The researchers then used semiconducting polymer materials to print photodiodes, which convert light into electricity. The entire process took about an hour.
Quarks are tiny constituents of protons, which themselves are some of the building blocks of atoms. The bottom quark is one of the six types of quarks that make up the menagerie of particles in the "standard model" that explains matter and their interactions
