Calculating magnitudes for forces is an important part of physics. When you’re working in one dimension, the magnitude of the force isn’t something you have to consider. Calculating magnitude is more of a challenge in two or more dimensions because…
Snakes with red and black stripes can range from deadly poisonous to completely harmless, so it’s important to be able to distinguish between different species. While bright markings on snakes generally indicate that you should keep your distance, some snakes…
Badgers and wolverines don’t resemble each other even though they both belong to the mustelidae family that also includes skunks, minks and weasels. Like other mustelids, they have five toes on each foot and use a musky odor to mark…
Scientific calculators simplify the process of inputting and calculating more complicated expressions than standard calculators. Ordinary calculators can handle factorials, but you have to enter them manually, and this can be time-consuming if you’re taking the factorial of a bigger…
Understanding and calculating percentages can help you in many ways: working out the correct tip at a restaurant, knowing how much you are saving on that mega sale or allowing you to interpret data from mathematical and scientific research. In…
When citing the strength of an acid, chemists often use the dissociation constant, Ka, but this number can vary by several orders of magnitude from one acid to another. To create a more manageable number, chemists define the pKa value…
Picture a desert in your mind, and you’ll probably envision a hot, dry landscape with intense sunlight. Right there, you have many of the key abiotic factors that influence the desert ecosystem. In addition, the type of soil is also…
In the autumn, the temperate deciduous forest trees lose their leaves in preparation for winter. From lack of chlorophyll, the leaves become many-colored, blazing with reds, golds and oranges. A unique factor of many of the trees in the deciduous…
Most objects aren’t really as smooth as you think they are. At the microscopic level, even apparently smooth surfaces are really a landscape of tiny hills and valleys, too small to really see but making a huge difference when it…
The letter E can have two different meaning in math, depending on whether it’s a capital E or a lowercase e. You usually see the capital E on a calculator, where it means to raise the number that comes after…
