Future tenses

There are several different ways in English that you can talk about the future. This page is an introduction to the most important ones:
- Predictions/statements of fact
- Intentions
- Arrangements
- Scheduled events

Predictions/statements of fact

The auxiliary verb will is used in making predictions or simple statements of fact about the future.

• The sun will rise at 6.30 tomorrow.
• Lunch break today will be 10 minutes longer than usual.
• In the year 2050 all students will have their own computers in school.
• If you help me, I will help you.
• Do you think she will come soon?
• You won't pass your exams if you don't start working harder.
• I know my parents won't let me go to the party.
• Will it snow for Christmas?
• I know she's sick, but will she be back in school tomorrow?

Mathematics

Irrational Numbers

An Irrational Number is a real number that cannot be written as a simple fraction.

Irrational means not Rational

Examples:

Rational Numbers

OK. A Rational Number can be written as a Ratio of two integers (ie a simple fraction).

Example: 1.5 is rational, because it can be written as the ratio 3/2

Example: 7 is rational, because it can be written as the ratio 7/1

Example 0.333... (3 repeating) is also rational, because it can be written as the ratio 1/3

Dynamic Electricity

Dynamic Electricity

The biggest difference between dynamic electricity and static electricity is the movement of charges or currents. The charges are constantly in motion when dynamic electricity exists. They are moving in different directions and are always forming currents. The electricity that exists in static electricity is composed of charges that are stationary. Static electricity is more stable than dynamic electricity and the charges that exist rarely move.

Electrical current is measured in amperes, or simply amps, a unit named after French physicist and mathematician Andre-Marie Ampere. Ampere's work in the field earned him the title "father of electrodynamics." While the amp measures the rate of actual movement, or flow, of electricity, the coulomb is a separate unit that denotes the amount of particles present. The ampere is one of the International System of Units' seven base units.

Amperes in a circuit can be measured using an ampere meter. This device can be connected to the load and will not affect the resulting measurement of electrical current. This is because the ampere meter itself has a resistance near zero.
