First Generation  Vacuum Tubes (1940-1956)

The first computer systems used vacuum tubes for circuitry and magnetic drums for memory

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

Factors of 5 are 1, 5

Factors of 11 are 1, 11

Factors of 21 are 1, 3, 7, 21

Factors of 37 are 1, 37.

Hence, according to the definition of a prime number, 21 is not a prime number as it has more than two factors.

Most modern banking systems are based on Fractional reserves.

Fractional-reserve banking is the practice whereby a bank accepts deposits, makes loans or investments, but is required to hold reserves equal to only a fraction of its deposit liabilities. Reserves are held as currency in the bank, or as balances in the bank's accounts at the central bank.

1. In a fractional reserve banking system banks can create money through the lending process.

2. A fractional reserve banking system is susceptible to bank panics.

3. Bank panics are a risk of fractional reserve banking, but are unlikely when banks are highly regulated and lend prudently.

Air Pressure can be defined as the pressure of air in the earth's atmosphere. It reaches a maximum of about 100,000 Pa near sea level and decreases as altitude increases.

The barometer is an instrument which is used for measuring Air pressure.

Physics instruments and their uses:

Barkometer  - - - Tanning liquors used in tanning leather

Bolometer  - - - Electromagnetic radiation

Spectrometer - - -  Properties of light.

A Badminton shuttle or a tennis ball.

A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide.

A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a Step-Up Transformer.

Conversely, a transformer designed to do just the opposite is called a Step-Down Transformer. 

Joseph F. Glidden - Father of Barbed Wire.

• Glidden was born in New York in 1812. He invented Barbed Wire in 1873 and was granted the patent on Nov. 24, 1874. After a three year battle over the patent, which he eventually won received a patent for the modern invention in 1874 after he made his own modifications to previous versions.
