Introduction Uranium-235 is less stable than uranium-238, but only slightly so. Both isotopes are highly unstable. U-235 has 92 protons and 143 neutrons in its nucleus, meaning it has a 1.55 neutron to proton ratio (N/P). In comparison, most stable elements have N/P ratios somewhere between 0.7 and 1.1. Uranium-238 has 146 neutrons in its […]

Introduction You might be surprised to find out that bones are considered to be tissue. After all, they are hard and rigid, unlike other tissues in the body which can bend or flex. However, this is just one way of looking at them. Another way of looking at it is that bones are a living […]

Introduction Aerospace engineering is a unique field that allows you to combine technical and analytical skills with creative problem solving. The opportunities for advancement within the industry are endless, so it's no wonder why aerospace engineers are some of the highest-paid professionals out there! But with so many different areas of expertise within aerospace engineering, […]

Introduction I'm sure you've noticed that different materials have different properties. For example, if you put a piece of wood in water, it will float while metal sinks. On the other hand, if you're trying to figure out how much weight your old truck can handle on its suspension system, then it's important to know […]

Introduction "When solid dissolves in water" you might ask. This is one of the most important questions in all of chemistry, and it's one we're going to answer for you here in this article. We'll talk about how temperature and pressure affect solubility, as well as why surface area matters when it comes to how […]

Introduction Why do nuclear power stations have to be decommissioned? If you’re reading this page, it’s likely because you already know that nuclear power stations need to be decommissioned. But if not, here are some facts about why they must be dismantled: Why are these plants dismantled? The cost of decommissioning. The process can cost […]

Introduction A spinning gyroscope is a classic demonstration of the effects of Newton's laws. When placed on a flat surface, it spins in circles due to the fact that its center of mass is not aligned with its axis of rotation. It's also known that gyroscopes are unaffected by Earth's gravitational pull. So why does […]

Introduction For the purposes of this article, I'm going to assume that you're familiar with both vacuums and fans. If not, here's a quick primer: A vacuum cleaner sucks air out of a room; it creates a low pressure zone which pulls in higher pressure air from behind it through a tube. This high-pressure air […]

Introduction Are you thinking of buying a new washing machine? It’s a big purchase, and there are many factors that go into choosing the right one. You have to consider what kind of washing machine will work best for your household, how much space you have in your laundry room, and even how tall you […]

Introduction Have you ever wanted to experience the effects of zero gravity on Earth? It's something that scientists are working on as we speak, and it will be possible in the future. But what exactly is an anti-gravity room, how would it work and would it actually be fun? Read on to find out! What […]
