Who was the first scientist to question the idea that atom were uncutable?

The first scientist to question the idea that atoms were indivisible was John Dalton, an English chemist, in the early 19th century. Dalton proposed that atoms were not actually indivisible, as previously believed, but rather could be rearranged in chemical reactions.

Studies the water and the water cycle?

Water is essential for life on Earth and exists in three main states: liquid, solid (ice), and gas (water vapor). The water cycle describes how water circulates between the Earth's surface and the atmosphere through processes like evaporation, condensation, precipitation, and runoff. Studying the water cycle is important for understanding weather patterns, climate change, and water resource management.

What city did Albert Einstein live in?

Albert Einstein lived in various cities throughout his life. However, he is most commonly associated with living in Bern, Zurich, Prague, Berlin, and ultimately Princeton, where he spent the later years of his life.

How did Alexander flemings discovery make a difference to your lives today?

Alexander Fleming's discovery of penicillin in 1928 revolutionized the field of medicine by providing the first antibiotic that could effectively treat bacterial infections. This discovery led to the development of numerous other antibiotics, which have saved countless lives by combatting various bacterial diseases and infections. Today, antibiotics continue to play a crucial role in modern medicine in treating infections and preventing the spread of diseases.

Who are the scientist that study about matter?

Scientists who study matter include chemists, physicists, and material scientists. Chemists focus on the properties and composition of substances, physicists study the fundamental nature and behavior of matter, and material scientists explore the structure and properties of materials.

Who discover antibiotic?

Joseph lister in 1928

This is debatable as some say it was Alexander Fleming in the same year

The discovery of penicillin is attributed to Scottish scientist and Nobel laureate Alexander Fleming in 1928. He showed that, if Penicillium notatum was grown in the appropriate substrate, it would exude a substance with antibiotic properties, which he dubbed penicillin.

Who are the scientists that discovered copper?

Copper is another one of those common materials whose use has been known since antiquity. Some of the earliest known mines in the world were for copper. The names of those who discovered it are lost to history.

Who was the first scientist to discover atoms?

Centries ago , a Greek philosopher , Democritus belived , that all matter was composed of extremely small particles to which he give the name Atomos meaning not to divide. During the early nineteeth centry an English scientist John Dalton , did some carefull experiment. His results convinced that atoms were not all alike .They differ in size , mass , and chemical behaviour , for example oxygen atoms are bigger and greater than hydrogen atoms.

Studies the atmosphere and weather?

A meteorologist uses what is known as super computers to study the atmosphere. It shows them where all the weather fronts and pressure systems are as well as all the moisture, winds, and the temperatures to come up with a forecast. There are a dozen to a couple dozen different weather models they look at to figure out what is going on in the atmosphere and what weather to expect.

What was Alexander Fleming's faveourite colour?

I'm not sure exactly, but probably a mouldy green... :)

Did Nikola Tesla go to school?

As a child Nikola manifested a full share of Duka's ingenuity, building among other things a bug-propelled engine. Much later he would mention that he had always the ability to see his ideas constructed in his mind, and in such detail that he could adjust and balance the parts. In school he absorbed languages quickly (English, French, Getman, Italian) and made an impressive showing in mathematics.

Scientists have found that properties of an element are more closely related to their?

electron configuration. The arrangement of electrons in an atom's electron shells determines its chemical properties, such as reactivity and bonding behavior. Therefore, properties of an element are more closely related to its electron configuration.

What school did gugliemo marconi go to?

Guglielmo Marconi studied at the Livorno Technical Institute in Italy, where he showed a strong interest in physics and electricity. He never attended a university.

Describe the contribution of early scientist in the development of periodic table?

Early scientists like Dmitri Mendeleev and Julius Lothar Meyer made contributions to the development of the periodic table by arranging elements based on their properties and atomic masses. Mendeleev's work led to the creation of the modern periodic table, which helped predict the properties of undiscovered elements and organize known elements in a systematic way. Meyer also made significant contributions by independently arranging elements in a periodic manner, which further supported the development of the periodic table.

What is the ability of light to eject an electron from a metal according to albert Einstein?

The ability of light to eject an electron from a metal is known as the photoelectric effect, as described by Albert Einstein. It occurs when photons of light transfer their energy to electrons in the metal, causing them to be ejected with a certain kinetic energy. This phenomenon provided evidence for the particle nature of light and helped establish the concept of photons.

Who discovered the pendulum?

The first person to hang a mass from a string and watch it oscillate back and forth is unknown. It's possibly the same person who invented the wheel and fire. The first person to sit down and really figure out the properties of a pendulum was Galileo Galilei.

When a scientist compares two or more objects what is he or she looking for?

When a scientist compares two or more objects, they are typically looking for similarities, differences, patterns, or trends that can help them draw conclusions about the relationship between the objects or the variables being studied. This comparison is crucial for generating data-driven insights and understanding the underlying mechanisms or behaviors of the objects under investigation.

What country did scientist Tesla come from?

Nikola Tesla was born in Smiljan, which was then part of the Austrian Empire and is now located in Croatia. Tesla was of Serbian descent.

Who is Michael farady?

Michael Faraday was an English scientist who made significant contributions to the fields of electromagnetic induction, electrolysis, and electrochemistry. He is best known for his work in the early days of electricity and magnetism, and his experiments laid the foundation for modern electromagnetism. Faraday's most famous discoveries include Faraday's law of electromagnetic induction and the laws of electrolysis.

How do you write up results in an experiment?

Results in an experiment should be presented clearly and objectively, using tables, charts, and graphs if applicable. Describe key findings, highlight patterns or trends observed, and refer back to your research question or hypothesis to discuss the implications of the results. Avoid drawing firm conclusions from the data without proper analysis and discussion.

Who are the different scientist involved in the origin of modern chemistry?

Some key scientists involved in the development of modern chemistry include Antoine Lavoisier, known for establishing the law of conservation of mass; John Dalton, who proposed the atomic theory; Dmitri Mendeleev, the creator of the periodic table; and Marie Curie, whose work on radioactivity had significant impacts on the field.

Which of these foods do scientists say will enhance the libido?

Foods like oysters, dark chocolate, and watermelon may be associated with enhancing libido due to their nutrient content. They contain compounds like zinc, antioxidants, and amino acids that can support healthy blood flow and hormone production, which are important factors for sexual desire and function. However, individual responses may vary, and it's best to focus on a balanced diet overall for overall health and well-being.

What is the physical appearance of Louis Pasteur?

Louis Pasteur was a French scientist with a prominent forehead, high cheekbones, and a long beard. He often wore glasses and had a serious expression in photographs.

What did Nikola Tesla look up to?

Nikola Tesla looked up to inventors and scientists such as Thomas Edison and Michael Faraday. He also admired the works of great thinkers like Leonardo da Vinci and Mark Twain. Tesla was driven by a desire to push the boundaries of science and technology.

What formula did tesla create?

First off, Nikola Tesla was brilliant. The Croatian-born engineer spoke eight languages, almost single handedly developed technology that harnessed the power of electricity for household use, and invented things like electrical generators, FM radio, remote control, robots, spark plugs, fluorescent lights, and giant machines that shoot enormous, brain-frying lightning bolts. He had an unyielding, steel-trap photographic memory and an insane ability to visualize even the most complex pieces of machinery the guy did advanced calculus and physics equations in his head, memorized entire books at a time, and successfully pulled off scientific experiments that modern-day technology STILL can't replicate. For instance, in 2007 a group of lesser geniuses at MIT got all pumped up out of their minds because they wirelessly transmitted energy a distance seven feet through the air. Nikola Tesla once lit 200 light bulbs from a power source 26 miles away, and he did it in 1899 with a machine he built from spare parts in the middle of the desert. To this day, nobody can really figure out how he pulled that off, because two-thirds of the schematics only existed in the darkest recesses of Tesla's all-powerful brain.

Of course, much like many other eccentric giga-geniuses and diabolical masterminds, Tesla was also completely insane. He was prone to nervous breakdowns, claimed to receive weird visions in the middle of the night, spoke to pigeons, and occasionally thought he was receiving electromagnetic signals from extraterrestrials on Mars. He was also obsessive-compulsive and hated round objects, human hair, jewelry, and anything that wasn't divisible by three. He was also asexual and celibate for his entire life.
