X-rays are a great tool for science, and so are lasers. So combine them and what do you got? Some awesome physics.
Nanotechnology is not a complicated notion, but it sure can sound fancy. If you've heard about it but you'd like to learn a little more, here's a quick primer on nanotech.
Learn how you can accomplish the various methods of interconnecting batteries, to make them suitable for your DC powered loads.
You are walking down the road when, "eek!" you fall into a huge pool of quicksand. There is nobody near enough to hear your cries for help. How will you escape? Can you really drown in quicksand? How can your practice escaping from quicksand from the safety of your own home? This recipe for Cornstarch Quicksand is very similar to the real thing, it is easy to make, and it even lets you walk on water.
The matter around you is composed of atoms but if we delve deeper we can find subatomic parts made of quarks and gluons. But they don't work according to our current understanding of physics.
A short explanation of the protocol for quantum teleportation, a quantum computing technique for transporting qubits over large distances.
Test which surfaces create more friction, see how strong friction is, learn how to reduce friction, and even discover the side effects of friction. There are sliding friction experiments, a phone book friction experiment, a way to make rice stick together, an experiment to create frictional heat, and lots more friction experiments for all ages.
What are Decibel levels and why are they so important? How can you measure them and when are they too "loud"?
Often a headache, time paradoxes are hard to fully delve into. Lets try and take a look at a few of them and see what we can learn from them.
When asked why the sky is blue, most people are able to come up with a vague statement about some gas called ozone being blue. The real answer, however, is much more interesting.
A detailed overview on the working of magnets whether you're looking for examination help, project guidance or knowledge to satisfy your curious mind.
In this article, we'll look at the derivation of Albert Einsteins famous equation E = MC2 show how you can come up with it using simple algebra and Pythagorean's Theorem.
Ballistics is a branch of mechanics which deals with the motion of projectiles launched into the air or space. Solving these type of problems involves using Newton's equations of motion
A basic easy learning and revision guide to chaos theory. I’ve tried to make this article easy to follow by using my own learning techniques i.e. very simple and without repetition.
This is only theory and not based on applied physics. I discuss this for the sake of expanding scientific thought on the subject of time.
A simple explanation of Albert Einstein's theory of special relativity and its effects on our understanding of space and time.
Galileo not only spotted new objects in the sky but also laid the groundwork for advancements in physics. What were they?
Already a complicated subject, black holes get even weirder when viewed through the lens of string theory. Read on for some odd possibilities for what black holes really are.
The relationship between temperature and volume is described by one of the pieces of the ideal gas law, also called Charles's law.
Galileo, the great prototype for all scientists, made many discoveries in physics and astronomy. But whose work did he build off of?
A summary of the historic experiment that was performed to determine the electrical charge of the electron.
Wheels are to be found everywhere and have been used since ancient times. But why do we use them and what is the science behind how they work?
The physics of a waterfall are curious. The second law of thermodynamics says that things tend toward a more disordered state. Is the second law saying that destruction (erosion) wins over creation?
Speed can be measured in many different ways and the instruments used to measure speed vary with the job.
Exploring the incorrect theories of lift and describing what really happens to an aeroplane wing in the air...
A magnet is an object that has a magnetic field strong enough to influence other materials. The molecules in a magnet are aligned to all face one way, which gives the magnet its magnetic field. Sometimes the molecules can align permanently, making a...
In 1905, Albert Einstein published four groundbreaking physics papers and announced his genius to the world.
Free physics problems help online with solutions on average velocity and average speed that walk you through each problem.
A summary of the key topics in nuclear reactor physics and a look at the worst nuclear accidents (Chernobyl and Fukushima).
Students usually make unnecessary mistakes in their examinations that cost them precious marks. These are some of the common errors they make in their electricity and magnetism exams.
Scientists have their own way to talk about black holes. Want to expand your ability to do just that? Read on to find out how...
Like many aspects of particle physics, electrons offer their own unique problems. Here is a sampling of some of the most interesting ones.
The first calipers were seen in China and were used for not only measurements but as a directional compass for ships at sea. This hub provides a list of different calipers and how they are used.
High rupturing capacity (HRC) fuses are totally enclosed fuses with definite known- high breaking capacity which have been developed after intensive research by manufacturers and supply engineers.
Dark matter and dark energy are still huge mysteries in astrophysics. Alternate theories exist to help explain them.
Water has some properties that can make it a good refrigerant. It also possesses some undesirable properties that makes its application as a refrigerant very challenging and inefficient to implement.
More than half of PhD students leave physics after earning their degree. The reasons include a lack of financial reward or job security.
TRIUMF is a facility for research in particle physics and accelerator-based science. It contains the largest cyclotron in the world and produces medical isotopes.
