Just Chat! / Re: Can we all be wealthy?
« on: 17/08/2021 15:24:52 »
Wealthy by definition means considerably above the average. If the average is everyone no one can be wealthy.
Gold and diamonds are a wierd thing, they only have the great value because people value them. Most people are not going to actually use a diamond or their gold for anything practical.

Physics, Astronomy & Cosmology / Re: How does gravity affect the efficiencies of pedaling a bike ?
« on: 04/08/2021 01:22:51 »The effort that your legs exert on the pedals is transferred to the back wheel by the chain as you ride a bicycle. This force has the ability to do one of three things.I have been over this before. The rotation of the bike is countered not only by the gravity of the rider who is forward of the rotation point, but the force on the pedals. When going up hill the strain becomes evident, much effort yet not travelling much distance, eventually the bike does not move and the rider is static whilst applying force to both pedals.
1. Push the bike ahead by rotating the wheel against the surface it is on.
2. Pull the bike into a wheelie by rotating the frame upwards around the pivot of the wheel. This may be seen in the practice of pulling a wheelie, which involves lifting the handle bars slightly and rotating the rear wheel with the pedals, resulting in a simultaneous forward and upward push, resulting in a wheelie. In such a case, the rider's weight may cross the pivot axle of the back wheel.

General Science / Re: Is science a religion.........well if not why is it defended as though it were

New Theories / Re: Gold may come from closer to home.
« on: 14/07/2021 16:25:54 »
Just by way of throwing a spanner in the works, much interest is placed in asteroid mining due to the abundence of valuable metals. Earth and the asteroids are made from the same material, just the asteroids didn't liquidise and the precious metals did not sink. Some of the gold on earth has to come from there. This must also mean that the core has the missing gold from the Earth's surface.

Just Chat! / Re: Mathematics is a decent science.
« on: 17/06/2021 00:32:25 »Hi.General maths is not a science, unlike economics or statistics which is a way of interpreting data through maths.
Why do you (Nakedscientists) have a thousand sections for life sciences (that was just a rough count) and not one section for Mathematics? Mathematics is everywhere but life sciences are only useful in a small number of real world situations.
Let's say Jane went shopping and picked up a thing that required her to evaluate an integral over a closed path on the complex plane. Alternatively consider John, who was out walking in the sunshine when he had a need to generate an infinite sequence of numbers that are co-prime but not primes. Where are these people going to get help with their serious problems?

COVID-19 / Re: How effective are the Russian and Chinese coronavirus vaccines?
« on: 24/05/2021 23:10:23 »
Effective is different for each person's viewpoint in my opinion. Astra zenica is 100 percent effective from stopping deaths according to the US study, but only 60 per ent effective at total prevention, but really the stopping of deaths is the important bit. The China vaccine is apparently 60 percent effective, yet has made no impact on the mortality rate in Chile as of today, with 40 percent totally immunised.
www.bbc.com/news/world-latin-america-56731801.amp
Given that 2 in 3 people never know that they had corona, the 60 percent figure of total effectiveness begins to look questionable.

Physiology & Medicine / Re: Does castration (physical or chemically induced) eliminate sexual desire?
« on: 27/04/2021 22:23:22 »That is the root of much in religion. We are not fornicating animals, but higher intelligences. The fixation on what is a biological reproductive neceßity is contrary to the conscious awareness and soul of humans. But the hormones get the better of people.Anecdotal evidence based on vicars' legs suggests that it doesn't work on pets, so there's no reason to suppose it would work on humans.
We'll never achieve peace and order and discipline while there is human sexual desire. Only when sex is thrown away, will real scientific civilisation become possible.

Physics, Astronomy & Cosmology / Re: What's the brightness of a star 16 times wider but half as hot as the Sun?
« on: 20/04/2021 22:06:01 »would a star with a radius 16 times that of the sun, but a surface temperature 0.5 times that of the sun, be more or less luminous than the sun?As a measure of lumens as in luminosity, given that star temperature is pretty much indicative of star colour, less energy than would be mathematically expected by the formula for surface area, that is to say less high end light. I am not sure of neutrons.
You can assume the surface area of a sphere is A=4 pi r squared
I cant seem to work this out. Can anyone help please?
Could a star have a diameter increaced of only 16 times yet be less luminous? Some sort of red dwarf?

If the brain stayed the same size but the body shrank Mankind would be phenomenally clever.
https://en.m.wikipedia.org/wiki/Brain-to-body_mass_ratio
Bigger people need bigger brains to keep parity, but also require more food and bodies seem to be subject to greater strain. Given that Mankind is in its evolutionary position because of the brain but is also in reaching in size due to the brain, we seem to be going down an evolutionary defeating path.

Physiology & Medicine / Re: Could human beings hibernate?
« on: 09/03/2021 22:53:02 »I have just remembered humans who cease to breath and circulate blood often are capable of being revived if they have been at very low temperatures even if it is a matter of hours without breath, so in a way hiberhation is possible in humans. I am not sure of the medical processes of decomposition or damage, really you need a medical person for that, but cold seems to stop this. I believe it requires a quick chill though.Technically, we can. Bears and even some primates are able to hibernate, which means us humans are also able to do so.Technically bears do not hibernate, the go into something called a torpor. I am unsure of the primates. Hibernation has the body temperature drop to ambient to the point that some animals drop just below 0c body temperature, the head being just above. The metabolic rate almost ceases unlike in bears.

Just Chat! / Re: I think I know why many don't accept global warming
« on: 24/02/2021 20:56:11 »Don't forget this is pushed into the face of the proletariat by idealistic monied people's with no real proof of the cause and lots of the "why don't you buy bamboo clothes and drive electric cars?".Does everyone not accept climate warming, the argument seems to be the cause.
Everyone accepts that the Earth's climate naturally changes over time. That's why the Earth has been through a succession of Ice Ages, and warm Interglacial periods, for the past 3,000,000 years. And much further back than that. Heck, 700,000,000 years ago, the entire planet was supposedly frozen all over as Snowball Earth. And in the later Carboniferous Period, the planet was a giant hothouse, with huge ferns and 18" dragonflies swarming all over.
All that is part of the natural order of things.
I think what gets people's goat is this: the modern suggestion, pushed in our faces remorselessly by the media, that whenever the climate changes nowadays, even a bit:
IT'S ALL OUR FAULT!
This suggestion is so ludicrous that can you wonder why people don't accept it. And suspect some conspiratorial motive behind it.
