(Microorganisms) are a general term for lower organisms that are tiny in size, simple in structure, and usually need a microscope to be observed.
Also called a Venn diagram, it was invented in 1881 by British mathematician John Venn. It's a way of visually showing the mathematical or logical relationships between sets. Usually, a rectangle represents the overall space, while circles or ovals represent specific sets. Overlapping circles show common elements, and separate ones indicate no intersection. You can easily see unions, intersections, and so on, though you can't list the exact elements precisely. Initially, this method mainly dealt with relationships among four sets, but later it was expanded to handle more sets. Nowadays, it's widely used in computer file management, teaching, and clinical thinking analysis.
Conditional probability is about how likely something is to happen given that you already know something else has happened.
Werner Heisenberg Profile Werner Heisenberg was a famous German theoretical physicist, philosopher, and one of the founders of quantum mechanics. Bio: Born on December 5, 1901, in Germany.
It's a chart that uses the height or length of bars with the same width to represent the amount of data. Bar charts can be horizontal or vertical, and when vertical, they're also called column charts. Besides that, there are different types of bar charts, like simple bar charts and stacked bar charts.
When two lines are cut by a third line, the two angles on the same side of the transversal and inside the two lines are called consecutive interior angles. When the two lines are parallel, consecutive interior angles are supplementary (they add up to 180°). Conversely, if consecutive interior angles are supplementary, then the two lines are parallel.
A satellite refers to a natural celestial body that orbits a planet and moves periodically along a closed orbit. Artificial satellites can generally also be called satellites.
Two lines a and b are cut by a third line c. The angles that are on the same side of the cutting line c and on the same side of the two lines a and b are called corresponding angles. When lines a and b are cut by a third line c, 'three lines and eight angles' appear, which include 4 pairs of corresponding angles, 2 pairs of alternate interior angles, and 2 pairs of same-side interior angles.
Place value, simply put, means that a number represents different amounts depending on where it stands in a row. For example, the number "2" is just two ones in the ones place, but two hundreds in the hundreds place. This is the basic principle in math of using digits and place values to represent numbers, and it's the rule behind the decimal system used worldwide and the binary system used in computers.
