5 Outstanding Tools of Science Over Time

The human race has always been fascinated with the world around it. The search for knowledge and understanding of the world has led to many discoveries and innovations.

There are many different tools that have been used in the past to make scientific discoveries.

Five o’clock tools that we will discuss in this article are just a few of the many inventions that have helped shape our understanding of the universe.

Inventions that changed the world

The telescope

The telescope is a tool for humans to explore the sky and space. One of the theories says that it was invented in 1608 by Hans Lippershey and has been used ever since to study stars, planets, comets, among others.

On the other hand, the history of the telescope from its other perspective is also a fascinating story. It all started with Galileo Galilei and his observations of the heavenly bodies.

He noted that the moon had craters, Jupiter had its four moons, and Venus had phases. Furthermore, he used his knowledge to create a telescope for himself.

Galileo is credited with inventing the first telescope in 1609. The invention was not known to have any practical use at the time, but it was an important step in the development of future devices that would be used to explore space.

Galileo Galilei was an Italian physicist and mathematician who is credited with inventing the telescope. Galileo published his findings in 1610, but it was not until 1609 that he first observed the moons of Jupiter and discovered four of Saturn’s moons.

Galileo observed that when a telescope is pointed at a star, the star’s image moves away from its original position on the opposite side of the lens. He also discovered that if you point a telescope at a planet, you can see what look like small stars near it.

These are actually stars too far away to be seen with the naked eye.

the microscope

The microscope is an instrument that helps in the observation of small objects. It was invented in the 17th century and has been used ever since, although it has undergone many changes and improvements.

The word “microscope” comes from a Greek word meaning “to see small things.”

The microscope is an optical instrument used to view objects too small for the human eye. One theory says that it was invented in the 17th century by Antonie van Leeuwenhoek and has been used ever since to study cells, bacteria, etc.

Another theory says that the history of the microscope dates back to the late 16th century, when Dutch eyeglass maker Zacharias Janssen invented a microscope that could magnify objects three times.

This was a big step in medical science because it allowed doctors to see more details and determine what was wrong with a patient.

Galileo is also known for his contributions to the history of microscopes. In 1609, he wrote about his observations with microscopes and published these observations in his book “Sidereus Nuncius”.

Galileo’s work helped pave the way for future microscopes that could magnify objects up to 400 times.

The thermometer

The thermometer is an instrument that measures temperature. It is designed to measure the temperature of a substance, such as air, water, or mercury, by detecting the energy it radiates.

The first person who came up with the idea of ​​measuring temperature was a Dutch scientist named Zacharias Janssen. Today we can get these devices at any hardware storebut then they were not common.

He came up with his theory in 1593 and then had to wait another 100 years before Galileo made it workable by inventing the thermoscope, which was an instrument that could measure changes in temperature.

Galileo Galilei was an Italian physicist born on February 15, 1564 and died on January 8, 1642.

His most significant contribution to physics is his study of the laws of motion, which also contributed to the development of calculus, and his experimental proof of the Copernican theory that the Earth rotates around its own axis and orbits around the sun.

In 1612 Galileo discovered that when he dropped two objects from different heights at the same time and then one fell apart from the other, it always followed that the one dropped first moved faster.

DNA fingerprinting

DNA fingerprinting is a technique that identifies people based on their DNA sequence variations with each other or a specific individual of interest.

Juan Vucetich is considered the creator of the world’s first fingerprint identification system. He was born in 1858, on the island of Hvar (now Croatia) and emigrated with his family, in 1882, to Buenos Aires.

Although Francis Galton is known as the pioneer of scientific research on fingerprints, Juan Vucetich’s contribution helped to coalesce this process and make it widely available.

This made it possible to identify people in any situation, regardless of the circumstances.

the x-ray machine

The history of the X-ray machine begins in 1895. Wilhelm Roentgen was studying cathode rays and noticed that they passed through some materials. He discovered that rays could penetrate materials and discovered what we now call X-rays.

He published his findings in an article called “On a New Type of Rays” which was published on December 28, 1895. The article discussed the properties of these new types of rays, as well as their discovery and Roentgen’s hope that they would be ” useful for examining opaque objects”.

This new type of radiation would eventually be called X-rays because it had been identified as a type of electromagnetic radiation with wavelengths slightly longer than those of visible light.

X-rays are produced by high-energy electrons colliding with metal plates or gases inside a tube. X-rays. This collision causes the electrons to release some energy in the form of short-wavelength electromagnetic waves.
