LOL. Coma Niddy parody: all about that space

Coma Niddy creates nice science rap music. He doesn’t always get the best of the rap out there, but he may be one of the guys that will be big in the science music industry. All about that bass is a parody of Meghan Trainor’s song All About That Bass. Neat!

Detecting those pesky neutrinos with Fermilab’s 14,000 ton NOvA detector

Neutrinos are very small particles, smaller than the electrons and they can travel through led for 2 years before hitting an led atom. Neutrinos have no charge and leave no traces, so they are hard to trap. Fermilab, IL, USA is generating neutrinos and shooting them 500 miles away, straight through the Earth crust to […]

Learn now what causes a sonic boom

A sonic boom is that continuous sound that you hear when an airplane is at or above the speed of sound. At the speed of sound the sound waves simply gather on top of each other right at the front of the plane and multiply their intensity hundreds and hundreds of times giving out that […]

How does the computer draw curved lines? It’s more complicated than you think

Cubic Bezier Curves – Under the Hood from Peter Nowell on Vimeo. I never knew how a computer draws curved lines, but now that I have seen it, I can say that it is an incredible process. What about games, where you have tons of polygons, about animations and so on? Man, do these computers […]

How do astronomers know what elements are stars made of?

Michel van Biezen, from iLectureOnline, explains how do astronomers know what elements are in the atmospheres of exoplanets or in the atmospheres of stars. It all has to do with emission spectra and absorption spectrum. Basically, a heated and ionized gas will output light in certain wavelengths and that is called the emission spectrum. The […]

What is the difference between anti-virus and anti-malware

As Linus, from TechQuickie, put it: both work int he same way as they fight viruses, but its the time scale they work on that matters. The antivirus deals with known threats and will update every once in a while while the dedicated anti-malware software, like MalwareBytes, will handle the immediate thread, the zero day […]

Learn physics with iLectureOnline.com: what are decibels (dB) and why we use them to measure sound intensity?

Decibels, written as dB, are a more convenient way to measure the intensity of sound. The actual measurements for the intensity of sound are in Watt/m^2 and, after you will see the upper and lower limits in w/m^2, you will understand why we use dB as units. First off, I want to praise Michel van […]

Lasers help us discover lost cities

DNews reported recently that lasers can and have been used to discover lost cities. It takes month and even years to discover lost cities and lasers can help reduce that time at least 10x. The technology used is LIDAR, a radar for lasers, which is good for penetrating dense vegetation. In 2013 researchers used LIDAR […]
