High up in Earth's orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to fragments of equipment...

Overcrowded orbits are making astronomers’ jobs harder.

Are we alone? It's one of the most basic questions of human existence. People have been trying to answer it for millennia in one form or another, but only recently have we gained the tools and…

Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate Ardem…

Logical inference from accepted truths leads to consistent reasoning. If two parties disagree then there is an error in their logic or no isomorphic map between their axioms. Is this true? Can axiomatic systems used in mathematics help in understanding disagreements between groups of people. Aristotle : “Axiom is that which it is impossible to make

My wife and I go out for dinner to our local restaurant. It gets us both away from distractions so that we can have some personal time together. I am very lucky to have a wife that discusses abstract thoughts, particularly when it comes to the relation in the restaurant.As I am draughting the pages

Since my younger years I have been fascinated with gravity. What is it ... why ... It feels mysterious. When I first watched Star Wars, the impact of seeing a planet with the low frequency sound rumbling in the cinema oozed power. It was like you could feel the massive planet through the screen. You

Time runs more slowly for people traveling at constant velocity relative to your position! This sounds like science fiction. It's not. What's more, it's not too hard to demonstrate. Outside of normal math, there is just one thing we need to know: Theorem 1 The speed of light is constant to all inertial observers. Imagine

I leave my desk to get lunch for my wife and I. In my shopping basket are a number of items … my mind wonders. I count four items. That’s two items each. I have immediately assigned a word that represents a number to these items without a moments thought. But what does this mean. At the checkout, the

Thoughts about Newton when walking our dog on a windy day The UK is experiencing Storm Amy. Its windy. Trees are swaying when we step out the door to walk our Black Labrador. This sparks thoughts about what generates motion. I think back to my younger years learning Newton's Laws of motion. How simple they

Thoughts about simple abstractions in counting ...

Your greatest danger is letting the urgent things crowd out the important.  We live in constant tension between the two. Important things “can wait.” Urgent requires immediate attention. Don’t let s...
