does anyone can cite 5 scientists and their contributions to science and technology?

Question

it's my science assignment... hoping someone can answer it....

Answer 1

Waldeyer discovered chromosome
Hans krebs propounded kreb's cycle
Anton van leewenhoek invented simple microscope
Wagner discovered nucleolus
Robert Brown discovered nucleus
cell theory propounded by Schleiden(botanist)&Schwann(zoologist)

Answer 2

André-Marie Ampère (1775-1836)

THE FRENCH PHYSICIST and mathematician André-Marie Ampère worked
at the beginning of the 19th century in Paris, France. He used
his mathematical and statistical skills to observe and measure
natural occurrences that had been discovered by other European
scientists. His greatest work involved the relationship between
electricity and magnetism, and the forces between conducting
wires. He also developed a new way of classifying chemical elements.
Ampère's name was given to the basic unit of electricity - the
ampere or amp.

Albert Einstein (1879-1955)

THE WORK OF German-born mathematician and physicist Albert Einstein
has made him one of the most famous scientists in history. His
theories of relativity introduced a revolutionary new way of
thinking about space, time, and the Universe. He also established
the relationship between mass and energy with the famous equation
E=mc^2 .
Einstein became a US citizen in 1940. He opposed war - but ironically
his theories were eventually used in the development of nuclear
bombs, the most destructive weapons known to humanity. Einstein
saw many of his theories confirmed experimentally during his
lifetime.

Marie Curie (1867-1934)

POLISH-BORN physicist Marie Curie and her French husband Pierre
are famous for their work on radioactivity. They were inspired
by the work of the French physicist Henri Becquerel (1852-1908).
Marie Curie was the first to use the term "radioactive" for substances
that emit invisible forms of radiation.
She also isolated two new radioactive elements: polonium and
radium. After Pierre's death, she took over his job as professor
of physics at the Sorbonne in Paris, the first woman to teach
there. She continued her research, looking for medical uses for
radioactivity. She was awarded the Nobel Prize for physics in
1903 and for chemistry in 1911.

Linus Pauling (1901-94)

THE US CHEMIST Linus Pauling is considered one of the greatest
chemists of the 20th century. His main work was on the nature
of chemical bonding. He introduced the concept of electronegativity,
and established the importance of hydrogen bonds in maintaining
the shape of proteins. For these achievements, he received the
Nobel Prize for chemistry in 1954. Pauling applied his ideas
on molecular structure to many problems, particularly in molecular
biology and medicine. His study of the structure of proteins
in the blood paved the way for the work of British biologist
Francis Crick and US biologist James Watson on the structure
of the DNA molecule.

Louis Pasteur (1822-95)

THE NEED to solve problems affecting the French silk, beer, and
wine industries led to some brilliant work by the French chemist
and microbiologist Louis Pasteur. He isolated and eliminated
two different bacteria that were causing disease in silkworms,
and also produced an accurate explanation for the process of
fermentation. He showed that food could be made safe by heat,
in a process now called pasteurization.
Pasteur is also known for his work on diseases that affect animals
and humans. He developed life-saving vaccines for treating anthrax
and rabies.

Ernest Rutherford (1871-1937)

THE NEW ZEALAND-BORN British physicist Ernest Rutherford laid
the foundation for the development of nuclear physics and modern
quantum theory. He investigated radioactivity and the nature
of alpha (positively charged) particles. His most significant
discovery was the nature of the structure of the atom. He realized
through his experiments that the positive charge of an atom is
concentrated at its centre in a tiny, dense nucleus.
Rutherford's work and leadership inspired two generations of
scientists. In 1908 he received the Nobel Prize for chemistry,
and in 1925 he became president of the Royal Society, London.
