General Science / Re: The journey to the red planet: does humanity need Mars colonisation?
« on: 30/12/2020 10:59:07 »Elon Musk's speeches available on Youtube have answered most of your questions. His goal is to make humanity a multiplanetary species in order to pass the "great filter". It's a prerequisite to form type 2 civilization in Kardashev scale. The starships are designed and built using methane as fuel for that very reason. Methane can be produced on Mars using materials available there, i.e. CO2, H2O, and sunlight.Is there any method how to take the appropriate amount of methane to get to the red planet without refueling?
As far as I know, scientists did no figure that stuff out.
Yes, I know that, but they most probably need to cary large amounts of oxygen and hydrogen to create water using a special machine. This has many logistical problems but will multiply in complexity as they are travelling the longest distance yet.

Just Chat! / Predictions?
« on: 30/12/2020 10:49:10 »
Dear all,
I am not sure if this topic belongs here, but I will give it a try.
There was a post on https://www.thenakedscientists.com/forum/index.php?topic=81038.0 that asked if there were any religious past predictions that have been fulfilled. I searced up on this and found two examples. Are these just chance, or deeper?
1) The Prophet ﷺ is reported to have said, ‘Verily you shall conquer Constantinople. What a wonderful leader will her leader be, and what a wonderful army will that army be!’ [Musnad Ahmad, Al-Hakim, al Jami’ al Saghir]¹ This has happened in 1453, but it could also be referring to the predicted future 'takeover'.
2)Michele de Nostredame, better known as Nostradamus, was the 16th-century physician and supposed seer, who has fascinated conspiracy theorists with his predictions for decades. Nostradamus' followers believe the French mystic predicted the rise of Adolf Hitler to power in 1933 as well as the Great Fire of London in 1666. Many also believe Nostradamus predicted the outbreak of the coronavirus pandemic.² He wrote,
“Near the gates and within two cities
“There will be two scourges the like of which was never seen,
“Famine within plague, people put out by steel,
“Crying to the great immortal God for relief.”
What do you think about these predictions? Can you shed some light on them? Do you have any other examples?

Famous Scientists, Doctors and Inventors / Re: Was Leeuwenhoek a scientist with no education?
« on: 30/12/2020 10:22:24 »
Then and now, if you had less education, or if you are young, you are not really going to be accepted into the scientific world. The example of the letter to the Royal Society, but no reply shows that there is a stigma relating to these people. If you submit a paper and you are young, there will be a lot of speculation, and if you ask for help, or even raise the subject of creating a new invention/theory, adults will say, "Well, you need a better and more complex understanding of blah blah blah." We need to change our thinking. I am experiencing this now, as I am only ----, and trying to contribute to science. I haven't' even looked at my ideas for a few weeks now, as a result of this. Do not succumb to the darkness...

« on: 30/12/2020 10:07:20 »Can you believe that Prue Leith has more than 10 honorary degrees!
A historian friend told me "You could get a PhD in history by choosing any date, reading all the contemporary newspapers, and writing a book about what happened in the world on one day. If I wanted to get a PhD in physics, it would take me 5 years to understand the question."
Said College dinner was to raise funds for a new building named after the former student who invented the jet engine. The professor of aeronautical engineering had taken over the post from one of Barnes Wallis's consultants on the Dam Busters bomb. Two of my undergraduate contemporaries were serving officers studying engineering on scholarships from the army and navy. Two others became directors of public health laboratories. Oddly, the historian in my gang later became secretary of the Institution of Electrical Engineers, where his detailed knowledge of Tudor England presumably contributed to the success of offshore wind power

What in your view is the easiest degree to get? They are all hard, but which is the least hard? Also, I like physics, but I am not good at maths. That is why I get put off. 
(I can't believe I was runner up for the physicist of the year award 2019 in my school and that I am having ideas about physics-related theories)! What a world...

Hello all,
The astronauts will have to transport many things to the Martian planet to survive: oxygen and hydrogen for fuel and water, lots of food, seeds and portable greenhouses, and other stuff. Instead of investing in expensive spacesuits and air filtration systems for capsules, could we at least try this technology underground. For example, we can take a disused (and safe) old mine, connect electricity, gas and water from above/below and use the air filtration system to provide fresh air. You can take the rubble from the excavation and use it for seawalls, weights, 'sandbags' and other things so that does not go to waste.
I have heard that some miners in America live underground, and have everything there to resemble a home: beds, sofas, stoves, heating, and fake windows!
If not Earth, why not the moon? It is far closer in case something goes wrong, and you can build extended facilities there, because of the availability of frequent supply shuttles from Earth.

« on: 16/12/2020 18:27:09 »Milk production at a dairy farm was low so the farmer wrote to the local university, asking help from academia. A multidisciplinary team of professors was assembled, headed by a theoretical physicist, and two weeks of intensive on-site investigation took place. The scholars then returned to the university, notebooks crammed with data, where the task of writing the report was left to the team leader. Shortly thereafter the farmer received the write-up, and opened it to read on the first line: “Consider a spherical cow in vacuum. . . .”Nice one!

Do you have a joke? Well, you are in the right place. Post all of your cringy joke on this page, and nowhere else. They could be science jokes or normal ones.

Plastic "'bags for life" also have the same problem. Have you ever noticed, some of the green bits on an Asda bag have white lines/patches in them? This is the evidence. Because of repetitive use, microplastic sheds off, and because the top layer is dyed green when shed, it will expose the white plastic underneath.

Dear Colin2B,
Thank you for the feedback; I will change the slides when I have some time.
I have learned, and I said this to my science class, when you hear a sound, your brain delays it so you can recognise the sound, and find out which direction it is coming from. Remember, you have 2 ears, so the sound waves coming from the left, will have to bend around your head to get to the right ear. This means that the sounds do not enter both ears at the same time. The brain just compensates.
