Why, in an atom, does the negatively charged electron not collapse into the positively charged nucleus?
If the nucleus of an atom is positively charged then why doesn’t the negatively charged electron collapse into it? To answer this we’re going to have to delve into the history of how our understanding of the atomic world has evolved, because the very nature of this question is based on a very old view of the atom. In the Beginning … When Ernest Rutherford, the New Zealand-born founder of nuclear physics, first...
Space is, famously, a pretty empty place. So, how is it possible to have weather there?
How have our ideas about atoms changed over the years? In this article we look at how our atomic models have developed over time. It is entirely probable that we aren’t there yet and our understanding of the strange world, that is the realm of sub-atomic particle, will change again at some time in the future. Although our article starts in the 1800s, the idea of atoms was around long before that. It is in Ancient Greece that we...
Why Do Light Bulbs Light Up? The answer to this one is in fact changing … In this article we look at BOTH Incandescent and LED Light bulbs.
In the summer of 1994 the States of Guernsey commissioned the design for a new Liberation Monument, to commemorate the 50th Anniversary of Liberation from the German occupying forces in 1945. The result is a truly amazing fusion of art and science. On the 9th May each year the shadow from the needle-like monument falls across a bench recording the events of that day at the exact same time they occurred.
In a physics lab at the University of Oxford there is a battery that has been powering a metal ball ringing two bells for a staggering 175 years and nobody knows why.
To have to be forced to even think about debunking this question is something of a sad indictment of our current zeitgeist. That said, the Moon Landing conspiracy, is one of those theories that seems to persist – so we’ll give it our best shot to explain the most pertinent objections that are often quoted as ‘proof’ that it was all fake, and nothing more than an attempt to humiliate the Russians and hoodwink the world in the cause of American glory.
When the “New Horizons” NASA space probe left earth on January 19th 2006, Pluto was the 9th and final planet from the sun. When it finally arrived 9 1/2 years later in July 2015 it wasn’t! By then Pluto had been down graded to a dwarf planet. So what happened to poor old Pluto to diminish it so?
According to NASA, America’s space agency, the skies high above the Earth are cluttered up with around 23,000 pieces of man-made space junk measuring 10cm or more across, zipping along at great speed and posing a threat to working satellites.
Grass stems and similar green leafy bits of plants make up the major part of the diet of many common animals, including cows, sheep, kangaroos and horses. If they can eat it, so why can’t we?
Did you know that your sense of smell and taste are connected? Also, as you get older, these senses can change ?
The problem with dinosaurs is that they lived a very long time ago- between 250 million and 65 million years ago – But is possible to tell what the lifespan of a Dinosaur might have been ?
There is something undeniably odd about a yacht doing 25 knots while sailing into a 15 knot wind. So, how is it that a yacht can travel faster than the wind ?
