• Nikola Tesla (Serbia/USA): Invented the alternating current electricity system and made pioneering contributions to wireless communication.

Dr. Fe del Mundo was a prominent Filipino pediatrician who was the first woman to be admitted to Harvard Medical School. She is known for her pioneering work in pediatrics and her efforts in advancing child healthcare in the Philippines.

Dr. Fe del Mundo was a Filipino pediatrician known for her work in the field of pediatrics. She founded the first pediatric hospital in the Philippines and developed the incubator and phototherapy treatment for jaundice.

The telephone was an invention in the field of telecommunications, which is a branch of electrical engineering.

Alexander Graham Bell was interested in sound because of his passion for helping the deaf communicate. This interest led him to invent the telephone as a means of transmitting sound over long distances, revolutionizing communication technology. Additionally, Bell's fascination with sound and speech led to his exploration of techniques for teaching speech to the deaf.

Alexander Graham Bell made significant contributions to physics through his invention of the telephone, which revolutionized communication technology. His work helped advance the understanding of sound, electricity, and waves, and laid the foundation for modern telecommunications. Bell's research also extended to areas such as hearing devices and aeronautics.

Alexander Graham Bell, a Scottish-born American inventor, completed his naturalization to become a U.S. citizen by filing a Declaration of Intention, residing in the U.S. for a specified period, and obtaining a Certificate of Naturalization. Bell followed the legal process required by the U.S. government to become a citizen.

1. "To every action there is always opposed an equal reaction." - Isaac Newton, third law of motion.
2. "An object in motion tends to stay in motion unless acted upon by an external force." - Newton's first law of motion.
3. "I can calculate the motion of heavenly bodies, but not the madness of people." - Isaac Newton, on human behavior.
4. "Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers." - Newton's law of universal gravitation.

That would be the decibel (dB), which is a measurement of how loud something is.

Edit: to be more precise, this is what a decibel is from wikipedia.
The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity (usually power or intensity) relative to a specified or implied reference level.

The decibel is commonly used in acoustics to quantify sound levels relative to a 0 dB reference which has been defined as a sound pressure level of .0002 microbar.

It would be challenging to list 20 foreign chemists and their discoveries in a concise manner. However, some significant foreign chemists and their contributions could include Dmitri Mendeleev (creator of the periodic table), Marie Curie (discovered polonium and radium), Linus Pauling (worked on the nature of the chemical bond), and Christian B. Anfinsen (studied protein folding).

Classifying things by observation can be done using your senses, such as sight, touch, taste, smell, and hearing. By carefully observing the characteristics, properties, and behaviors of objects or organisms, you can classify them based on their similarities and differences.

Atomic theory explains that matter is composed of small particles called atoms, which are indivisible and retain their identity in chemical reactions. It also explains how atoms combine to form molecules through bonds and how these interactions determine the properties of matter.

John Dalton is credited with laying the foundation for atomic theory in the early 19th century. He proposed that all matter is made up of tiny indivisible particles called atoms, which combine to form compounds in fixed ratios. Dalton's work paved the way for modern understanding of the structure and behavior of atoms.

In 1880, Bell received the Academie francaise, representing the French government, in Paris.

Alexander Graham Bell worked with Thomas Watson, an electrician and Bell's assistant, while building the telephone. Watson was integral in helping Bell refine the design and testing the first successful telephone call in 1876.

Alexander Graham Bell's telephone worked by converting sound waves into electrical signals, which were then sent through wires to a receiver that converted them back into sound. The telephone relied on the principles of electromagnetism to transmit and receive these electrical signals, specifically by using a metal diaphragm and an electromagnet to convert sound waves into electrical signals and vice versa.

Some of the key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century, J.J. Thomson, who discovered the electron, Ernest Rutherford, known for his gold foil experiment that led to the discovery of the nucleus, and Niels Bohr, who developed the planetary model of the atom.

Albert Einstein, known for his theory of relativity which revolutionized our understanding of space, time, and gravity. Marie Curie, for her pioneering research on radioactivity and the discovery of two elements, polonium and radium. Stephen Hawking, for his work on black holes and the nature of the universe, popularizing complex scientific ideas for a wider audience.

Albert Einstein did not invent the light bulb. The incandescent light bulb was actually invented by Thomas Edison in 1879. Einstein was a theoretical physicist known for his contributions to the field of physics, particularly his theory of relativity and the famous equation E=mc^2.

Ask him your self :P

Yes, Alexander Graham Bell applied the scientific method in his work on the invention of the telephone. He conducted experiments, collected data, formed hypotheses, and tested his theories in a systematic way to develop his invention.

Alexander Graham Bell attended the University of Edinburgh and the University College London. He did not attend a traditional college to earn a degree, as his education was mainly through independent study and tutoring.
