Summarize the following:
You can experiment with paper sizes, but if in doubt, a standard-sized (8.5 x 11 inches) will do.

summary: Lay a rectangular piece of paper down lengthwise (landscape-style).

Summarize the following:
Newton's first law tells us that any object in motion will continue to move in the same direction at the same speed unless another force acts on it to change its motion. If an object is stationary, it will remain stationary. This first law is sometimes referred to as the law of inertia. This law states that an object moves with a constant velocity (speed and direction) unless there is a nonzero (unbalanced) net force acting on it. An object that is not moving has a net force of zero acting on it. As the force acting on an object increases, the acceleration of the object increases. Force alone does not determine the acceleration of an object; the object's mass also plays a critical role. The larger the mass of an object, the slower it will accelerate. This relationship can be explained using the formula F = ma where "F" is the force acting on the object, "m" is the mass of the object, and "a" is the acceleration of the object. Another way to think about this law is that an object will not accelerate unless there is an unbalanced (or net) force acting on it. The third law states that every action has an equal and opposite reaction. When a force acts on an object, there is a force of the exact same magnitude that pushes back in the opposite direction to the original force. For example, when you sit down on a bench, you are exerting a downward force on the bench, but the bench is exerting an equal upward force on you. This law states that all forces come in pairs. Conservation of energy states that "energy can be neither created nor destroyed." In other words, energy remains constant in an isolated system. The same goes for momentum and angular momentum: in an isolated system momentum and angular momentum remain constant. It's important to note that an isolated system is one in which there are no outside forces acting on it. In reality, an isolated system doesn't really exist, but it is a useful model to describe the basic principles of the physical laws of nature.

summary: Define Newton's first law of motion. Understand Newton's second law of motion. Learn Newton's third law of motion. Know the laws of conservation of energy, momentum, and angular momentum.

Some experts advise using sexual positions that encourage deep penetration, such as a rear-entry position, when trying to conceive a boy. The logic behind this is that ejaculating during deep-penetration sex places the sperm as close as possible to the cervix, giving the fast-moving male sperm an advantage. With shallow penetration, sperm may be deposited farther from the cervix, which means that the more durable female sperm (which can survive longer in the vagina) may have the advantage. Male sperm, which are more fragile than female sperm, tend to die faster in the acidic environment inside the vagina. Giving the female partner an orgasm can improve the chances of the male sperm because during female orgasm, extra cervical fluid is released. This makes the environment more hospitable to male sperm, increasing the chances that they make it to the egg alive. There are also claims that the orgasmic contractions can help push the sperm into the cervix faster. Just remember, these aren't proven by science. Some research suggests that the older the parents are, the higher the chances are of having a girl. Therefore, if you're trying for a boy, it might be best to start early. The chances are highest for a woman to conceive a boy before age 30. It's age 35 for men.
summary: Have sex in a rear entry position. Try for a female orgasm. Consider having a baby before your reach 30 or 35.
