Chemistry igcse batteries

There are two main types of battery: As the reactants inside them become used up in chemical reactions, the output from these batteries gradually falls. Rechargeable batteries Rechargeable batteries usually maintain a constant output until just before they go flat.

Born —[ edit ] Juan Caramuel y Lobkowitz — was a Spanish scholastic philosopher, ecclesiastic, mathematician, and writer. He was a precocious child, early delving into serious problems in mathematics and even publishing Chemistry igcse batteries tables in his tenth year.

Blaise Pascal — was a French mathematician, physicist, and religious philosopher who wrote a treatise on vibrating bodies at the age of nine; he wrote his first proof, on a wall with a piece of coal, at the age of 11 years, and a theorem by the age of 16 years.

He is famous for Pascal's theorem and many other contributions in mathematics, philosophy, and physics. Carl Friedrich Gauss — made his first ground-breaking mathematical discoveries while still a teenager.

Also at the age of 3 watched his father add up his accounts and corrected him. In the words of E. Bell he, "read it as easily as other boys read a pirate yarn". Ignoring his teachers, he himself sought out and studied the works of Lagrange and Abel.

Ted Kaczynski born May 22,the "Unabomber", was a child prodigy who excelled academically from an early age. Kaczynski was accepted into Harvard University at the age of 16, where he earned an undergraduate degree, and later earned a PhD in mathematics from the University of Michigan.

He became an assistant professor at the University of California, Berkeley at age 25, but resigned two years later. He has won many major awards in mathematics, including the Fields medal.

Ruth Lawrence bornpassed the Oxford University interview entrance examination in mathematics at the age of 10, coming first out of all candidates sitting the examination. At the age of 13 she became the youngest to graduate from the University of Oxford in modern times.

Graduated with Specialized Honours B. Mathematics from the University of Toronto in at age Akshay Venkatesh bornwon a bronze medal at the International Physics Olympiad at 11 years of age. Finished his PhD at 20 from Princeton University.

Associate Professor at Erik Demaine bornbecame an assistant professor at MIT at 20 years of age. At an age of 13, he developed a mathematical formula for perpetual calendar calculations, which also mentions historic dates observed on various types of calendars.

At an age of 15 years, he designed a low-cost artificial leg with an ability for knee and ankle movement. He has also developed missile technology at an age of She started reading at age 1, [25] began learning college-level calculus at age 7, [26] and at age 13 became the youngest student to complete work for a bachelor's degree from Montana State University in Mathematics.


Several mathematicians were mental calculators when they were still children. Mental calculation is not to be confused with mathematics. This section is for child prodigies largely or primarily known for calculating skills.

Zerah Colburn — had a major display of his ability at age eight. Jerry Newport bornautistic calculating savant at age seven, already using calculus to compute third and higher roots, title holder of "Most Versatile Calculator", won in Self-discovered much of the number theory in elementary school—perfect numbers, Fibonacci, etc.

Truman Henry Safford — could square 18 digit numbers at the age of ten years; later in life, he became an astronomer. In order to enter the Institute, candidates had to take a difficult entrance exam, which included an essay.Doc Brown's detailed CHEMISTRY REVISION NOTES.

Organic chemistry is a branch of chemistry connected with compounds of hydrogen and carbon (hydrocarbons). Hydrocarbons It is a class containing only hydrogen and carbon bonded together covalently.

They can form very long chains, and can form chains linked by 5/5(19). A series of free IGCSE Chemistry Lessons (Cambridge IGCSE Chemistry).

Tips and notes for English, . Mathematics and science Mathematics Born – Juan Caramuel y Lobkowitz (–) was a Spanish scholastic philosopher, ecclesiastic, mathematician, and writer.

He was a precocious child, early delving into serious problems in mathematics and even publishing astronomical tables in his tenth year. Cells and Batteries Cells and batteries supply current which always passes in the same direction and are thus sources of direct current.

The underlying principle of operation in a battery is an ELECTROCHEMICAL REACTION i.e. a chemical reaction that produces electrons.
