what would happen if the Earth was tipped up on its axis?
The world would spin so the equator was spinning at nintey degrees or so to where it is now. Every twenty four hours it would still spin West to East as it does now, but the Sun would not rise and set every day. I think it would only do that when the Earth was mid way between when either pole faced the Sun. Because the Earth rotates round the Sun. So the North or North East or North West would face the Sun for half of the year and the South, South East and South West for the other half.
So what would happen to the poles? Even now, because the Earth is tipped at an angle and doesn’t rotate vertically, we get summers and winters. So there twenty four hour days in the polar summer, and twenty four hour nights in polar winter. If the Earth was tipped over more the twenty four hour days and nights would last for months. The side away from the Sun would be colder, the side towards it would be hotter. Perhaps all the ice would melt at one pole and freeze much more at the other? Who knows? I’m sure scientists would have the answer. Thankfully we don’t face that question. Sadly we do face climate crisis. We need to sort out the current situation. How? I don’t know the answer to that. But perhaps we should follow what teachers put on school reports. We must try harder?!
Something I wrote a couple of years ago on Facebook :
I keep seeing posts, don’t use this, don’t eat that, they are full of toxic, carcinogenic, genetically modified ingredients. BUT does anyone ever question where this information comes from? There does not seem to be scrutiny of whether things are FACT or FICTION.
Firstly everything is made of chemicals..because they are made of atoms or molecules of various elements. Even the wind is made if chemicals, because it is in fact gases like Nitrogen, Oxygen, Carbon Dioxide and other elements. The only thing that us not chemical is energy, like light (photons) and energy on the electromagnetic spectrum.
So when someone writes there are chemicals in something that is FACT.
Some are harmful and some are good, it can depend on the amount of something in it. That seems to be where the problem lies. Especially where people believe in homeopathic remedies, where the original active ingredient is so diffuse it sometimes can not be measured any more but people still believe in its effectivness (the placebo effect).
There seems to be an idea that even trace amounts of chemicals can do harm, in some cases that is true, we have all seen films where terrorists plan to put nerve agents in water supplies, and they show a tiny phial of stuff and say this thing can kill a million people. But it is not true that all things in trace amounts can be harmful. It’s these scare stories that worry me. I love science and finding out things. I am not an expert, so I tend to ask people who know or look up things on Wikipedia or Snopes to see what the facts are.
I think we should all question things, but try and follow the facts, not being scared to seek the truth. Certain newspapers will say something is poisonous one day, and then say it is a cure for everything the next. Sometimes you can’t take things at face value.
Science is important, without it we would be back in the stone age.
So how can you tell the Earth is a sphere? The ancient Greeks worked it out ( I don’t remember the name of the person who did).
The experiment was to put a stick in the sand at or near the equator, so it would have a tiny shadow directly underneath the it at mid day as the Sun was directly overhead.
If you place a stick upright, at 90° to the Eaths surface either North or South of the equator, the stick casts a shadow at mid day. (Look at the hands of a clock the hands move round in the same way). Say the equator is 3pm and the Sun is overhead, you would get no shadow, then as you go further away from the stick at the equator you get increasing angles (see diagram). Eventually at the poles the shadows would be at their longest.
So how can you tell its a sphere? The angles add up. You can calculate the curvature of the planet from these simple experiments. The ancient Greeks got very close to calculating the circumference of the Earth. Their calculations were only a small percentage out on their measurement.
Betelguse the star is shrinking.
Fainting they say.
On the shoulder of Orion,
it’s getting fainter.
obese and middle aged?
Perhaps your sides are about to split.
Red Giants can’t stay inflated.
They use up all their fuel.
Puffed up and massive.
Suddenly they can pop like a balloon.
Not enough energy to push out,
the star will fall inwards,
In a million years or so?
You might be a Supernova!
Make a Betelguse nebula.
Then Orions shoulder will flower.
And we may see an exploding star.
The first in the Milky-way since 1604.
Sodium nitrate, sulphur and carbon. Mixed together make gun powder. That is the explosive mixture they put into fireworks. The ratios of the different elements determine the burning characteristics. Strontium makes red, sodium yellow, copper green, magnesium bright white, other elements make different colours. Cobalt? Possibly blue. The elements burn at different temperatures. Each element, when heated, excites electrons in its atoms. As they cool down again photons of light are given out (emitted). The colour depends on the energy the photons release. Bear with me it gets complicated! In the same way you can tell what elements are in the sun or other celestial objects by their emission lines. If you look at a spectrum (rainbow of colours), given out by the light of the sun there are gaps, these correspond to gases like Hydrogen and Helium.
I don’t know enough science to explain properly.
Anyway the fireworks have stopped so I might go to bed.
Quantum physics. I like reading books about it. But I don’t really understand. Schrodingers cat is in a box. There is a phial of poison in the box with it, but no one knows if the cat us alive or dead unless you open the box. What causes the phial to break depends on entangled electrons…… Which is where I’m lost and can’t remember what I read.
Books I would recommend, that I’ve had for years. In Search if Schrodingers Cat, by John Gribben, and In Search of Schrodingers kittens, by the same author. He also wrote In search of the Edge of Time.
So it’s up to you. It’s a tricky subject, but worth looking into.
Blogging seems to be all sorts of things. I follow poetry, science, history, art and all sorts of other subjects. I post pretty much anything I’m interested in. I try and write things that are interesting, sometimes short stories or poems, other times about my art.
I started out thinking it would purely be about painting and drawing. But I suddenly realised that I wanted to include more than that. My writing and grammar skills are not honed. I used to write essays in English or History classes, but that was on the subjects on the syllabus. When I got to Art school I had to write essays and a thesis, so blogging came slowly. I hope what I write is enjoyable or interesting.
