This video teaches the basics of Ohm's law, which is an important equation in electrical engineering. The three variables which are used in this equation are V, which stands for voltage, I for current, and R for resistance. The equation for the law itself is I=V/R. This law defines the relationship between these three very important electrical properties. The host of the video further explains what voltage, current, and resistance are and how they work in relation to an electrical current. Gi...

In this tutorial, we learn how to do a quick workout with super sets. First exercise you can do is a squat to cable row. Use a resistance band to do this by placing it around a post or having someone hold it. Back up to build resistance, then plant your feet parallel and hip width apart. Squat down, then bring the elbows back as you go back up. After you do ten of these, immediately switch to a deadlift underhand row. Hold a dumbbell with your hands, then bring the weight down and bring it ba...

A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.

You don't need a pricy gym membership or a personal trainer to achieve a celebrity-worthy body. In fact, all you really need to tone up at home is a yoga mat, a few good exercise videos, and some weights. After all, your own body is often more than enough to act as its own resistance during workouts.
Adding resistence in the form of weights to your workout is the best way to increase the difficulty of the exercise. This forces your muslces to work harder and makes you burn more fat (which is always a good thing).
Halo 2 and the original Xbox may seem obsolete all these years after the release of the Xbox 360 and Halo 3.
