The Environment / Could pollution from vehicle tyre wear contribute to ill-health?

« on: 16/12/2020 14:05:14 »

OK  the news today was about a coroner has ruled that air pollution contributed to the death of a nine-year-old girl in the first case of its kind in the UK. we hear about car exhaust pollution, but can the real reason be tyres? Some 5.8 grams per km of harmful particles produced by tyres during driving due to wear, Particulate matter is microscopic solids or liquid droplets that can be inhaled and exposure to this type of pollution can affect both your lungs and your heart.
Measurements found that 5.8 grams per kilometre of harmful particles are emitted by tyres as they wear when a car is being driven.
That compares to 4.5 milligrams per kilometre produced from exhaust pipes.
How come this isn't being addressed?  Also shoe trainers are made from problematic materials including nylon, synthetic rubber and plastic they wear down creating the same problematic particulates into the air the same way, so are we blaming all onto just one area of concern when we should be addressing the bigger picture here?

Physiology & Medicine / When asked to think of a number, what colour is it?

« on: 20/11/2020 13:37:51 »

When someone says think of a number,
what colour is it?
What colour do you see it in your minds eye?
How do we assign  colour to shapes or numbers?
Do you see it in colour or just a clear shape.?

Physics, Astronomy & Cosmology / Expanding universe

« on: 08/12/2013 15:18:18 »

If the universe is expanding... is the space between the fundamental particles that make up atoms expanding also? so are we expanding? and if not why only the space of the large expands?

Plant Sciences, Zoology & Evolution / what happens to C02 if left in a fish tank for some time?

« on: 02/02/2012 16:53:23 »

if you had a sealed fish tank with a small brick of carbon dioxide at the bottom and let it Sublimate at room temp of say 21 c and at average ground level, would the gas stay at the bottom of the tank with air above it for all time or would it eventually mix with the the rest of the air (gas) in the tank?

Physics, Astronomy & Cosmology / Could Mount Etna's eruption set clocks 15 minutes fast?

« on: 01/08/2011 11:36:56 »

ok this is a bit of a puzzle can we blame the volcano? as thousands noticed that their clocks were running 15 minutes fast. The fast forward time keeping has affected a wide spectrum of digital clocks and watches - from computers through to alarm clocks. was it due to the quartz crystal oscillators in the clocks with very precise frequency 32,768 Hz some how getting zapped by a natural "EMP" electromagnetic pulse?

Physics, Astronomy & Cosmology / is time conected directly to mass?

« on: 12/06/2011 14:56:25 »

for example is time compressed at a black hole due to its mass and its immense gravitational influence or will time remain the same? Could time be connected directly to the mass of matter, even a photon might have a very small mass therefore creating its own time?
Could there be areas in the universe where there is no mass/ matter in it.. a total absence of everything? Would time still exist there?

Physics, Astronomy & Cosmology / expanding universe

« on: 22/04/2011 17:32:50 »

OK its a fact that the universe is expanding  but is the space between atoms expanding at the same rate too? and if not why did matter ie atoms and the space between them stop expanding shortly after the big bang?

Physics, Astronomy & Cosmology / Can the moon cause freak weather effects on Earth?

« on: 11/03/2011 17:06:52 »

The Moon will pass closer to the Earth than it has in almost a decade next week and it is believed by some that the 'supermoon' could cause havoc with the world's weather cause earth quakes and tsunami, though most scientists don't think so,  my question is what is the measured gravitational force of the moon on the earth and how much closer would the moon need to be to cause the world problems?

why don't we study people that never get ill?
is it chance or genetics?

Plant Sciences, Zoology & Evolution / can cats see green light?

« on: 02/12/2010 18:14:13 »

I was playing with my cat this eve with a Red laser pointer Output wavelength: 650 nm. and the cat would chase it all over the floor but when i used the green laser pointer 532 nm which is brighter, the cat would look past it and take no intrest in it at all, but when switched back to the red he would continue on running after it, so are cats blind to green light?

Physics, Astronomy & Cosmology / is gravity at the centre of the earth the same as it is on the surface?

« on: 12/11/2010 14:22:49 »

is gravity at the centre of the earth the same as it is on the surface?
in other words  if you was to drill a hole through to the centre of the earth and measure the Gravitational forces in steps along the way would it be the same as it
is on the surface of the planet or proportional to the mass passed along the way or is gravity infinite?

Physiology & Medicine / How do memories of dreams and memories of real events differ?

« on: 25/10/2010 16:14:23 »

In other words,  if you have a memory of a dream and a memory of a real event, do they share the same part of the Brain? and if they do how do we tell what memory is real and which is not?

Physics, Astronomy & Cosmology / Would an anti-matter magnet attract iron?

« on: 01/10/2010 17:30:02 »

Phil asked the Naked Scientists:
   
Assuming it was possible to create a magnet made of anti-matter, would it attract or repel anti-matter iron / normal Iron?

Would you have anti-magnetism or is magnetism the same in an antimatter universe as it is here if so why?

What do you think?
