How To: Plant garlic in your garden for a plentiful harvest

David Epstein provides tips and shows garlic lovers how to plant garlic in their very own garden. It is best to grow garlic in the fall season from the months of September to November when the temperatures are cooler. Some people grow garlic in the spring, but it’s been found that growing garlic in the fall time will give a better crop. To begin, gather some plantable garlic bulbs making sure that you find ones that are either organic or from a seed catalog. At all cost, avoid conventional ...

How To: Use the laws of logarithms

ProfessorElvisZap teaches you about the laws of logarithms. When x is positive, meaning 0<x. x times y equals y times x. This is the commutative property. x times (y times z) equals (x times y) times z. This is the associative property. x times 1 equals x. This is the multiplicative property. x times x to the power of -1 equals 1. This is the multiplicative inverse property. You can use these properties with addition: a+b=b+a, (a+b)+c=a+(b+c), a+0=a and a+(-a)=0. A logarithm is a homomorphism...

How To: Apply the 1st Law of Exponents

In this video tutorial the author explains the concept of 1st Law of Exponents using an example. He shows that when we add polynomials the exponents does not change but when you multiply two polynomials their exponents change. He says that the new exponent is the sum of the first polynomial exponent and the second polynomial exponent. He further demonstrates this with a good example. This video clear shows with an example about the concept of the 1st Law of Exponents using it to multiply two ...

How To: Apply the 6th Law of Exponents

This is a video tutorial in the Education category where you are going to learn how to apply the 6th Law of Exponents. The 6th law of exponents says, to raise a product to a power, you can multiply each of its factors by the same power. For example if you have (acm) to the power x, that will be equal to the product of (a to the power x), (c to the power x) and (m to the power x). How is this done? (acm) to the power x is same as (a to the 1, c to the 1 and m to the 1). What we are doing is, w...

How To: Understand the basics of exponent laws

Before you can effectively use exponents, it is necessary to understand the laws behind them. First, in order to multiply a number raised to an exponent, by that number raised to another exponent, just add the exponents: for example, 2^5 * 2^2 is 2^(5+2), or 2^7. In short, a^m * a^n = a^(m+n). Similarly, dividing a number raised to an exponent by that number raised to another exponent can be done by subtracting the exponents: a^m / a^n = a^(m-n). To raise a number raised by an exponent to ano...

How To: Understand Newton's second law

In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...

How To: Draw a room with stairways using complex levels

Have you ever secretly pined away for a career in interior design, even though you're currently stuck in law school because, well, your parents forced you and gave you no other option? Because law school can be a bit rigid in terms of what you learn (pretty much it's just facts and figures and learning sound logic), it's important to indulge your creative side ever once in a while.

How To: Make magnets float down a steel tube

Mr.G in the episode 3 of "Summer snow fall" explain the experiment for eddy currents and lenz law by using general house hold items like copper tubes of different dia., 2-neo themium magnets attached together and a ball bearing magnet. At first he took the big diameter copper tube and drop the neo-themium magnets, they fall slowly without touching the surface of the copper tube as they are like freely falling from space with less gravity, for the next time he took small diameter copper tube a...

News: Say Goodbye to Almonds—Common Pesticide Additive in Orchards Linked to Honey Bee Colony Collapse

The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.

How To: Experiment the law of inertia

Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...

News: What Is a White Hat Hacker?

In recent weeks, some people have been shunned from the Null Byte community because they expressed "black hat" aspirations. This is because Null Byte is the "white hat" hacker training/playground. Although most of us think we know what that means, it does beg the question; "Who and what is a white hat hacker?"

How To: Understand deductive reasoning

In this video, Robert Ahdoot becomes "surfer dude" and shows us the ways of deductive reasoning, as relating to geometry. He begins with a simple example of a syllogism, taking two premises and using them to form a conclusion. This is called the Law of Syllogism. This concept is then used for geometric statements. If two angles are complementary, they sum to 90 degrees. If two angles sum to 90 degrees, then they are acute. By the law taught, it can be said that if two angles are complementary...

How To: Ride a bike in traffic

This video is a tutorial on how to ride a bike in traffic. The first rule is to obey the law. You would need to follow the laws of traffic as though you were driving a car. If there is a bike lane, use it. It is not a good idea to use the sidewalk as that is reserved for walkers and runners. Ride predictably by signaling your turns. The video tells the viewer which side of the road to ride on, and also provides tips. He also discusses how to ride with another cyclist. This is a very informati...
