Introduction It's 2020, and you're sitting at home watching the news. The anchor reports that a terrorist group has detonated a suitcase nuke in downtown Los Angeles. You might wonder: How much damage could this do? How many people would die? What would happen next? A lot of questions, but fortunately we have some answers. […]

Introduction I'm a little confused about the chemistry of combustion. I know that when a hydrocarbon (like methane) burns, it combines with oxygen and forms carbon dioxide and water. I also know that in an absence of air, the hydrocarbon doesn't burn completely and leaves carbon monoxide, which is harmful for our health. Does this […]

Introduction If you've ever been in an airport, chances are you've seen a homeless person asking for change. While most of us choose to ignore them and pretend they aren't there, some people take action and try to help those who need it. A few years ago, these good Samaritans started a trend called 'suspended […]

Introduction PCR is the process by which short strands of DNA are replicated many times over. The resulting pieces become the template for a new strand but do not themselves have any specific function. These strands are used to determine whether or not your sample contains certain nucleic acids that you're looking for (like viral […]

Introduction Compressed air is roughly 78% Nitrogen, 21% Oxygen, 1% Argon and small percentages of other gases. By using a zeolite molecular sieve to separate compressed air, the primary constituent/s are removed depending on the size of the pores in the sieve. This means that if you have a pore size of 4 angstroms (*) […]

Introduction If you have enough solar panels and battery banks, you will be able to power a 7.5hp three phase motor. The average solar panel is rated at approx 200 watts per panel, so in your case you would need approx 250 x 200 = 50,000 watts of solar panels. Inverters are measured in watts, […]

Introduction An Auxiliary Pump is a block that generates power from Fuel or Oil when supplied with a Redstone signal. It takes one bucket of fuel or oil per second and provides 80 RF/tick for each bucket consumed. The Auxiliary Pump must be placed next to an Electric Pump , but does not have to […]

Introduction Drifting is a fun way to take your car to the next level. It's also a great excuse for you and your friends to hang out in your driveway and smoke cigarettes (if you're into that sort of thing). But what do you need to drift? Well, there's a debate raging across the nation […]

Introduction I've heard it a million times: "Is mechatronics harder than chemical engineering?" The short answer is yes. But what does that mean, exactly? I'll address this question in detail below. Yes, mechatronics engineering is harder than chemical engineering. As a student in a mechatronics engineering program, you are likely aware that the field is […]

Introduction If you have ever seen an aircraft close up, you may have noticed that some of them have strange chunks of metal hanging out at the back. This is because in aircraft, counterweights use heavy metals to offset weight. In aircraft, counterweights use heavy metals to offset weight. When it comes to aircraft, counterweights […]
