10 Marvelous Discoveries in Science

Science has been around as long as humans. What would the world be without science? We would have no knowledge about movement. We wouldn’t be able to explain the world around us. Science allows us to explain different events in the universe. It brought many great thinkers together, all in the hope of finding answers to the unknown. Here’s a list of 10 most marvelous discoveries in science.

10 Marvelous Discoveries in Science

The 10 Marvelous Discoveries in Science:

10. Gravity

Gravity is better known as force. The first to make its discovery was Newton. The legendary story goes that Isaac Newton was once sitting under an apple tree, when an apple fell on his head. It led him to wonder what was the force that pulled the apple to the ground. Thus the concept of gravity was born. Then a physicist named Albert Einstein used gravity to explain why planets orbit around the sun. This led to the discovery of a lot of different theories such as dark matter and quantum gravity.

9. Photons

Photons are essential particles to light and radiation and they are just about the most marvelous discoveries in science. It is both described as a wave and a particle. However it has no mass, and can travel at the speed of light. The theory of photons was not popular until Albert Einstein looked into it. He explained the photoelectric effect building off from Gilbert Lewis in 1926. Lewis stated that light was made of particles, making this a fundamentally important particle to physics.

8. Quarks

Quarks make up protons and neutrons. Protons and neutrons make up matter. In recent times one of the most marvelous discoveries in science is the top quark. It was discovered in 1995 leading to a new revolution in physics. There are six quarks and each have a fractional charge and a color charge.

7. Conservation of Mass

Antoine Lavoisier made the first discovery of the law of conservation of mass. The law is that mass cannot be created or destroyed and remains constant. This finding led to a lot of discoveries in the 19th century. However in general relativity mass and energy is much more complicated and deals with a vast field.

6. Radioactivity

Isotopes are atoms of the same element but have different number of neutrons. When isotopes are not balanced they are radioactive. Radioactive are among the most marvelous discoveries in science. When particles are emitted from the nucleus of an unstable atom it is radioactivity. Not all radioactive particles are bad though. Some are quite useful and necessary.

5. Bohr Model

In 1915 Niels Bohr proposed a model of the atom. It is an atom where the nucleus is positively charged and is orbited by negatively charged electrons. This is a modification of the Rutherford model which was proposed earlier. This model contains an error which is corrected by modern quantum mechanics. This model is used to bring out the most important properties of the atomic structure. It’s a simple model of the atom.

4. General Relativity

In 1915 Einstein published the Theory of Relativity. This theory is a combination of Newton’s Law of Gravity and Special Relativity. The theory is that all laws of physics are the same for non accelerating observers and the speed of light is the same no matter the speed of the observer in a vacuum. Space and time are woven together known as space-time. Einstein found that massive objects disrupt space-time. An example would be the orbit of mercury. The orbit of mercury is changing over time because of the space-time of the sun. Mercury could collide with earth in a few billion of years.

3. Antimatter

Antimatter is almost like science fiction. It is made up of antiprotons, antineutrons, ad positrons. Stable antimatter does not exist though. When combined with equal amount of matter it will convert into energy. This energy is dangerous and deadly. Positrons are the opposite of electrons. Antimatter is greatly studied by physicists.

2. Newton’s Laws of Motion

One of the most marvelous discoveries in science ever made is the three laws of motion. An object remains in a state of motion until an external force is applied to it. The second is force equals mass times acceleration. The third and most well known is for every action there is an equal or opposite reaction. These three laws are responsible for changing our understanding of physics and the universe.

1. Higgs Boson

The most recent discovery in physics is the Higgs Boson. This is also known as the ‘god particle’ because it was very hard to find and extremely rare. It was in 2013 that Higgs Boson was discovered. The Higgs Boson is a particle in the Higgs field. The theory was first made public in 1964 by Peter Higgs and Francois Englert. The Higgs field is a field full of energy that transmits mass to everything that that travel through the field. They predicted that this is how everything in the universe has mass. In CERN there was a large hadron collider that shoots protons into each other. And as they collide they break into subatomic particles and the Higgs Boson is one of these particles.
