FAMOUS FOREIGN SCIENTISTS

Thomas Edison (1847 - 1931)

He is the author of a large number of inventions, but the most well-known one is the electric bulb. Among other discoveries of Thomas Edison there are telegraph devices, phonograph, carbon transmitter, direct current generator, universal electric motor, and more.

Thomas Edison’s Light Bulb

Thomas Edison is most well-known for his invention of the light bulb. Contrary to popular belief, Edison did not invent the light bulb; it had been around for a number of years. The electric lights at the time, however, were unreliable, expensive, and short-lived. Over twenty distinct efforts by other inventors the world over were already underway when Edison entered the light bulb invention race.

By creating a vacuum inside the bulb, finding the right filament to use, and running lower voltage through the bulb, Edison was able to achieve a light bulb that lasted for many hours. This was a substantial improvement, and one that led with more improvements, to making the light bulb practical and economical.

Of course, Edison also later invented the entire electric utility system so he could power all those light bulbs, motors and other appliances that soon followed.

Alexander Graham Bell (1857 - 1922)

During the experiments he carried out with the telegraph, Bell came up with the idea of the telephone.

The inventor of one of the most popular devices today thought that the telephone was intruding, which is why he did not have one in his workplace.

TELEPHONE

A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user.

Sir Alexander Fleming (1881 - 1955)

During the World War I Fleming worked as an army medical corp.He is the inventor of penicillin that prevented a lot of soldiers from being infected.The discovery of penicillin managed to significantly boost the evolution of medicine industry.

PENICILLIN

Penicillins are a certain collection of antibiotics that eliminate infection causing bacteria. Also known in short as pen or PCN, they originate from a type of fungi called Penicillium fungi. They are used in the treatment or prevention of many different bacterial infections, usually caused by Gram-positive organisms.

They are well known in medicine as they are one of the first types of antibiotic used for major infections and diseases, and are still used regularly in modern medicine. Penicillins are all β-Lactam (Beta-Lactam) antibiotics, which are antibiotic molecules with a β-Lactam nucleus.

Albert Einstein (1879 - 1955)

One of the greatest scientists of the 20th century is the author of numerous inventions and theories that transformed a lot of concepts linked to space and time, with the most important discovery being the theory of relativity. Other discoveries of Einstein include the photoelectric effect and the Einstein calculator.

E = mc2

E = mc2 is the world’s most famous equation—a mathematical formula with the power to transcend the barriers of language and culture. Matching its popularity is its deceiving complexity. Its symbols, although easily recognized, embody concepts contrary to the way things seem to be.

Evangelista Torricelli (1608-1647)

The famous Italian physicist and mathematician is the author of the barometer (scientific tool used in the field of meteorology to estimate atmospheric pressure), built in 1643. It would be interesting to note that a number of Italian Navy submarines were named after the inventor.

BAROMETER

A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.

FAMOUS FILIPINO SCIENTISTS

Pedro Flores

Inventor of YO-YO one of the most popular toy in the world.

The word yo-yo is a Tagalog word, the native language of the Philippines, and means 'come back.' In the Philippines, the yo-yo was a weapon for over 400 hundred years. Their version was large with sharp edges and studs and attached to thick twenty-foot ropes for flinging at enemies or prey. People in the United States started playing with the British bandalore or yo-yo in the 1860s.

It was not until the 1920s that Americans first heard the word yo-yo. Pedro Flores, a Philippine immigrant, began manufacturing a toy labeled with that name. Flores became the first person to mass-produce yo-yos, at his small toy factory located in California

YO-YO

A yo-yo is a toy which in its simplest form is an object consisting of an axle connected to two disks, and a length of string looped around the axle, similar to a slender spool. It is played by holding the free end of the string known as the handle (usually by inserting one finger in a slip knot) allowing gravity or the force of a throw to spin the yo-yo and unwind the string (similar to how a pull string works), then allowing the yo-yo to wind itself back to one's hand, exploiting its spin (and the associated rotational energy)

Fe del Mundo

Inventor of Incubator=Fe del Mundo, the first Asian to have entered the prestigious Harvard University's School of Medicine, is also credited for her studies that led to the invention of incubator and jaundice relieving device. Del Mundo, an International Pediatric Association (IPA) awardee, is an alumna of the University of the Philippines (UP) College of Medicine. Since 1941, she has contributed more than 100 articles to medical journals in the U.S., Philippines and India. In 1966, she received the Elizabeth Blackwell Award, for her "outstanding service to mankind". In 1977, she was bestowed the Ramon Magsaysay Award for outstanding public service.

INCUBATOR

An incubator is a special cot that keeps your baby warm and sometimes controls the moisture level (humidity) around her. Some incubators have lids, some don't. Some have overhead heaters.

Gregorio Zara

Famous Filipino Scientist. Gregorio Zara - famous Filipino scientist Gregorio Y Zara. Filipino scientist Gregorio Y. Zara (D.Sc. Physics) invented, made improvements to, or discovered the following: invented the two-way television telephone or videophone (1955) patented as a "photo phone signal separator network"; discovered the physical law of electrical kinetic resistance called the Zara effect (around 1930); invented an airplane engine that ran on plain alcohol as fuel (1952).

VIDEOPHONE

A videophone is a telephone with a video display, capable of simultaneous video and audio for communication between people in real-time. Videophone service provided the first form of videotelephony, later to be followed by videoconferencing, webcams, and finally high-definition telepresence.

FELIX MARAMBA

Felix Maramba built a coconut oil-fueled power generator. He also is the developer of one of the world's most profitable biogas systems.

Other Achievements:

Felix Maramba is the president of the Philippine Association of Flour Millers, Inc. Felix Maramba wrote: Biogas and Waste Recycling, The Philippine Experience.

COCONUT OIL-FUELED POWER GENERATOR

Benefits of Biogas Systems:

Less pollution of the air and waters

Improves local economics

Increases productive of land by recycling systems of farming

Roberto del Rosario

Karaoke Sing Along System: Karaoke is a Japanese expression for singing along to a famous record with the vocals removed. Roberto del Rosario described his

sing-along system as a handy multi-purpose compact machine which incorporates an amplifier speaker, one or two tape mechanisms, optional tuner or radio and microphone mixer with features to enhance one’s voice, such as the echo or reverb to stimulate an opera hall or a studio sound, with the whole system enclosed in one cabinet casing.

KARAOKE SING ALONG SYSTEM

KARAOKE is a form of interactive entertainment or video game in which an amateur singer sings along with recorded music (a music video) using a microphone and public address system. The music is typically a well-known popular song minus the lead vocal. Lyrics are usually displayed on a video screen, along with a moving symbol, changing color, or music video images, to guide the singer.
