Cosmic Questions : How big is the universe? ; How fast is it expanding? ; Where is the force coming from? ; Where is the centre of the universe?
We consider some BIG questions in this article, however beware, not all the questions have what you might consider satisfactory answers.
Does anyone know what atoms and molecules actually look like?
That matter is composed of atoms we take for granted … but can we hope to unravel what they actually look like ?
Who ‘discovered’ the Atom ?
The simplest of experiences can hatch eureka moments. Legend has it that despite all his inherited wealth and global travels, the ancient Greek philosopher Democritus hit upon one of the most fundamental of ideas in physics while sitting in the comfort of his own home.
What Causes the Pull of Gravity ?
One of the most common and baffling science questions is “how does gravity work?”. If you too find yourself confused then rest assured you’re in good company … even Sir Isaac Newton admitted he was baffled by gravity. In this article we look at Einsteins solution to this conundrum.
Is it true that water empties out of sinks anti-clockwise in the northern hemisphere ?
It’s often said that water draining out of a sink or bath swirls down the plughole anti-clockwise in the Northern Hemisphere and clockwise in the southern hemisphere .. but is that really true ?
Why doesn’t the Earth’s magnetic north pole lie at the North Pole ?
If the fact that all magnetic compasses don’t actually point to the geographical North Pole comes as a shock to you then what we discuss below will blow your socks off, because magnetic north actually moves year by year AND the poles have even flipped in the past; North is South & South is North!
Radio Ga Ga
We take radio and television signals for granted now. But if you really think about it radio waves really are a strange phenominon … invisibly beaming sound from one point to another through and around solid objects !
We are Stardust …
We are Stardust … the chemical elements that make up our bodies, originated, with one exception, in the turbulent body of a star
Chaos and Disorder – or Why does it always happen to me ?
Why do so many things seem to go wrong ? Sometimes you suspect that the universe is out to get you! We need to look at some scientific theories surround something called Entropy or the “The laws of thermodynamics”
Ground Source Heat Pumps
Ground Source heat pumps promise to supply most if not all the heating required for any new house without drawing ANY energy from the Electricity Grid! What are they? Ground source heat pumps use solar energy naturally stored in soil, bedrock and groundwater as a heat source. They do require electricity to operate, but efficiently produce up to five times as much heat energy for every unit of electricity they use. How does it work?A...
How does an Atomic Clock Work ?
The most accurate time piece today is an Atomic Clock. But how does it work & what’s the theory behind it ?
How does a Microwave Oven Work ?
Microwave ovens are part of everyday life. But how to they work?
What’s stopping us falling through the floor?
Why is it that we don’t fall through the floor? What’s stopping us ? A stupid question, surely ? … not really when you consider what an atom is made up of.
Photo Voltic Cells (Solar Panels)
Solar cells, or photovoltaic cells, convert energy from sunlight into electricity… but how? What principles lie behind this technology?
The Origin of the Yard, Meter and Kilo
How many of us have a foot a foot long ?
What are the origins of some of the measurements we use today.
