In “Magnetic Movie” the filmmakers use actual scientists’ discussions about the nature of magnetic fields but then illustrate it with sound and animation to give you a better idea as to what they look like. It’s freaky in the most beautiful of ways: it makes us think of all the things we can’t see but that do shape the world around us.
The Telegraph in the UK ran the twenty of a much longer list evidently published in BBC magazine. We’d like to see it, but why are they holding out on the answers to the UNanswerable questions. Typical grown up behavior, telling you only the stuff they already know.
Where is the safest place to stand outside in a thunderstorm?
Tall, pointy objects standing alone in an open space are more likely to get struck by lightning but it’s by no means a certainty. Sometimes the flat ground next to a tall tree can be hit. A car or other enclosed metal structure is the safest place to be in a thunderstorm. Failing that, a ditch, trench or group of shrubs of uniform height is better than nothing. Keep away from boundary areas between dissimilar terrain (water and land; rock and earth; trees and fields). Also keep at least five metres away from metal objects or other people as lightning will often jump from one object to another.
Why do identical twins have different fingerprints?
Although identical twins share the same DNA, they don’t look identical cell-for-cell, because not every aspect of your physical appearance is rigidly determined by your genes. Fingerprints are formed semi-randomly as the foetus develops in the womb andare affected by such things as chance fluctuations of hormone levels. Similarly, the pattern of freckles and moles on the skin is caused by random mutations and will vary between identical twins.
Is the human race still getting taller?
The average height, at least in Western society, is increasing because of better childhood nutrition and sexual selection. But the tendency of women to find men taller than six feet (183cm) more attractive can’t be extrapolated upward, and people above 6ft 2in (188cm) are much more likely to suffer back problems. Above 6ft 8in (203cm), and the heart strains to pump blood round the body.
Why do I feel cold and shiver when I have a fever?
A fever is when your body increases its internal thermostat, found in the hypothalamus. If you exercise hard or it’s a hot day, your body temperature might increase, but the thermostat remains at around 36.8°C. When you feel hot the hypothalamus tries to correct this with sweating and increased blood flow to the skin. But with a fever, it is the thermostat that has risen. This means your body temperature is now below 36.8°C, so you feel cold and shiver, to try and raise your temperature. The higher body temperature may help fight infection by speeding white blood cell production and slowing bacteria reproduction.
What is OK short for?
The most popular theory is that OK comes from ‘oll korrect’, a deliberately misspelled writing of ‘all correct’. It was popularised in Boston newspapers around the 1840s when it was fashionable to go around spelling things incorrectly for humorous effect. Legend also has it that New York Democrats later adopted the abbreviation to promote their candidate Martin Van Buren – the initials ‘OK’ were derived from his nickname, Old Kinderhook.
Why can’t we just fill in the ozone hole with man-made ozone?
The sheer scale of the notorious hole – or, more accurately, depleted region – in the Earth’s ozone layer over the Antarctic beggars belief. At its peak each September, it spans an area bigger than the continental United States, and tens of millions of tonnes of ozone would be needed to fill it up again. Simply creating that amount of ozone, let alone getting it where it’s needed, would be astronomically expensive.
Why do fingers and toes wrinkle when left in water?
The waterproof coating on our skin gets rubbed away from areas of our bodies like our hands and feet that are frequently in contact with objects. If you immerse yourself in water with a lower concentration of dissolved salts than that of your cell contents, water will be absorbed by osmosis and cause your skin cells to swell. Since they are anchored to the tissues below, they are forced to corrugate to accommodate this.
What is a hiccup?
A hiccup comes from an involuntary contraction of the diaphragm, producing asudden intake of air. The glottis (the vocal apparatus of the larynx) slams shut at the same time, so that the column of air strikes the closed glottis to produce the characteristic, onomatopoeic noise.
Is there an easy way to prove the Earth is round?
Yes, travel. Because the Earth’s surface is curved, you’ll notice that different constellations of stars are revealed.
Can you have a fish out of water?
Yes. Several species of fish can breathe air and crawl on land. There are about 50 species of flying fish, too.
Why is sea air good for you?
It isn’t, particularly. In Victorian England, seaside resorts got a reputation for having healthy air – maybe in comparison to the era’s city smogs. The seaside’s “bracing” smell is caused by a chemical produced by coastal bacteria, present in very low concentrations. But a study last year found that sea salt can react with chemicals in marine exhaust fumes to worsen the atmospheric pollution in a busy port.
Do plants die of old age?
Given good conditions, some plants can live for ever. It takes a change in external conditions to finish them off. But annuals die soon after seeding.
Does chewing gum really stay inside you for years?
No. Chewing gum is indigestible but it doesn’t have any magic property that allows it to escape the normal digestive transit. Three days is the usual limit.
Where do phobias come from?
Around 10 per cent of the population suffer from phobias. Some may be triggered by a traumatic event while others are linked to physical problems. Studies suggest that simple phobias are partly genetic while others may be due to cultural history. For example, a fear of spiders may be passed down from the Middle Ages when spiders were associated with the plague, as victims’ deserted homes became shrouded in cobwebs.
Do men have cellulite?
Yes. It’s not just women who are cursed with orange peel skin, although in men cellulite tends to be in different places, usually around the neck and abdomen.
Can germs catch germs?
Yes. The germ would be an even smaller organism that attacks its host germ from within.
Why do I get more car sick in the back?
It’s probably because you don’t have such a good view of the horizon. Motion sickness occurs when the balance mechanism in your ear registers movement while your eyes are telling you that you are stationary.
Could we live on water and supplements?
No. As well as vitamins and minerals we need carbohydrates, fats and proteins for energy and cell repair.
Do hot drinks cool you down?
Yes. They make your body think you are hotter than you really are so you sweat more and that leads to heat loss.
What would happen if there were no Moon?
The most immediate effect (other than the lack of moonlight, of course) would be on the Earth’s tides. With only the Sun’s gravitational influence, the difference between high and low tides would be reduced dramatically – as would tidal drag, which slows the Earth down at a rate adding about 0.002 seconds to the length of a day each century. Long term, the effects would be far more serious. The climate of the Earth is sensitively dependent on the 23.5° tilt of the Earth’s axis, and without the stabilising presence of our relatively huge Moon, the gravity of the other planets would produce big changes in this angle – as it does with Mars, whose tilt changes by 60° over a few million years.
We’ve a bit neglectful of our folding and glueing as of late, yet papercraft figurines fill up our bowl with joyful memories.
Our friend Bill Horberg sniffed these out for us. Nancy may be old school, but the idea of breaking with the rules of reality will forever feel new to us. They call it “the fourth wall” and here the artist shatters it. Whatever he’s doing, he’s making us laugh!
So you want that big sound of many people making music at the same time but just don’t have enough friends who bang drums? Just invite some robots over and start jamming.
Songs about ice cream trucks and unusual animals being played on funny instruments (tuba, theramin, stylophone, claviola) and accompanied by a batallion of self-playing musical instruments, ie: musical robots. It’s a very happy experience.
What if they were tearing down your house, and all you could do was make the sounds of them tearing it down — but make them perfectly? That’s what the Lyra Bird does. It’s as if it has a tape recorder built in it’s throat. You have to see it, umm, hear it, to believe it. It mashes up all the sounds it hears together too, so one moment it is singing a song of a neighboring fowl and then a split second later it sounds like a camera shutter or a chain saw. Can you say “whacky?”
These images were taken from the Japanese space capsule Selene in 2007. It may be eight minutes without any sound, but sit back and watch things from a different perspective. If you aren’t glad you did, we will put your money back in the bowl.
The EarthRise image Wide Shot was taken from near the North Pole, and the Arabian Peninsula and Indian Ocean can be observed on the Earth.
The EarthSet image Tele Shot was taken from near the South Pole, and we can see the Australian Continent (center left) and the Asian Continent (lower right) on the Earth.
