father of genetics
Mendel was born into an ethnic German family in Heinzendorf bei Odrau, Austrian Silesia, Austrian Empire (now Hynčice, Czech Republic), and was baptized two days later. He was the son of Anton and Rosine Mendel, and had one older sister and one younger. They lived and worked on a farm which had been owned by the Mendel family for at least 130 years.[3] During his childhood, Mendel worked as a gardener, studied beekeeping, and as a young man attended the Philosophical Institute in Olomouc in 1840–1843. Upon recommendation of his physics teacher Friedrich Franz, he entered the Augustinian Abbey of St Thomas in Brno in 1843. Born Johann Mendel, he took the name Gregor upon entering monastic life. In 1851 he was sent to the University of Vienna to study under the sponsorship of Abbot C. F. Napp. At Vienna, his professor of physics was Christian Doppler.[4] Mendel returned to his abbey in 1853 as a teacher, principally of physics, and by 1867, he had replaced Napp as abbot of the monastery.[5]
Besides his work on plant breeding while at St Thomas's Abbey, Mendel also bred bees in a bee house that was built for him, using bee hives that he designed.[6] He also studied astronomy and meteorology,[5] founding the 'Austrian Meteorological Society' in 1865.[4] The majority of his published works were related to meteorology

The molecular scattering of light
Nobel Lecture, December 11, 1930
The colour of the sea
In the history of science, we often find that the study of some natural phenomenon
has been the starting-point in the development of a new branch of
knowledge. We have an instance of this in the colour of skylight, which has
inspired numerous optical investigations, and the explanation of which, proposed
by the late Lord Rayleigh, and subsequently verified by observation,
forms the beginning of our knowledge of the subject of this lecture. Even
more striking, though not so familiar to all, is the colour exhibited by oceanic
waters. A voyage to Europe in the summer of 1921 gave me the first
opportunity of observing the wonderful blue opalescence of the Mediterranean
Sea. It seemed not unlikely that the phenomenon owed its origin to
the scattering of sunlight by the molecules of the water. To test this explanation,
it appeared desirable to ascertain the laws governing the diffusion of
light in liquids, and experiments with this object were started immediately
on my return to Calcutta in September, 1921. It soon became evident, however,
that the subject possessed a significance extending far beyond the special
purpose for which the work was undertaken, and that it offered unlimited
scope for research. It seemed indeed that the study of light-scattering might
carry one into the deepest problems of physics and chemistry, and it was this
belief which led to the subject becoming the main theme of our activities at
Calcutta from that time onwards.
sir isaac newton
With all the things that Isaac Newton did some of his most renowned works was with that of gravitation. Newton was one of the foremost scientific intellects so fall time. Newton is also considered one of, if not the most influential astronomers of all time (web 1). Besides his contributions to this field he gave physicists an easier way and more comprehendible way of doing physics. This was due to these three laws that he came up with that where named after him. They were as follows:
Newtonís First Law
A body at rest will remain at a rest or a body in motion will remain in constant motion unless a force is applied to it.
Newtonís Second Law
F=ma
(Force= Mass x Acceleration)
(One of the most used equations in physics)
Newtonís Third Law
For every force there is an equal and opposite reaction.
Newtonís first law applies to anything that is in motion or standing still.
thomas (alva) edison
Thomas (Alva) Edison was one of America’s most important and famous inventors. Edison was born into a time and place where there wasn’t much technological advancements. His inventions helped a lot of things quickly change in the world. His inventions contributed to many inventions today such as the night light, movies, telephones, and records and CDs.
Edison is most famous for the development of the first electric light bulb. Like I said Edison was born into a time where America wasn’t very developed. He was born, and electricity had not been developed. But thanks to Edison when he had passed away on October 18, 1931 whole cities were lit up in electricity. For electricity, much of the credit goes to Edison.
Some of his inventions were improvements on other inventions, like the telephone. He didn’t “invent” the telephone he just made it better. Some of his inventions he did try to invent, like the light bulb and the movie projector. The one he is most proud of was pretty much an accident--the phonograph.
Edison invented and improved upon things that changed our world. Some of the things he invented, he did by himself. Some he did with other people. Just about all his inventions are still around today and are commonly used. It was important to Edison that he created and invented things that people could use in their everyday life.
