Camera-Stabilizing Technology Used In Spoon For Parkinson’s Patients

Who: Calico is an independent R&D biotech company established in 2013 by Google Inc.
What: Camera stabilizing tech used in spoon
Where: 1180 Veterans Blvd, South San Francisco, California, United States
How: The Liftware stabilizing handle built in sensors that detect hand motion and a small onboard computer that distinguishes unwanted hand tremor from the intended movement of the hand. To counteract any tremor and stabilize the utensil, the computer directs two motors in the handle to move the utensil attachment in the opposite direction of any detected tremor. Clinical studies have shown that the Liftware utensil reduces shake on average by 70%, so you can worry less about spilling and enjoy your meal.

Thomas Alva Edison Quotes

Thomas-Alva-Edison-Quotes---Science-Pivot

 

Thomas Alva Edison. American prolific inventor and businessman.

Quote: Many life’s failures are people who did not realize how close they were to success when they gave up.

Edison invented tremendous devices that widely influenced life of the entire world, encompassing the phonograph, the motion picture camera, and a durable, practical electric light bulb. Dubbed “The Wizard of Menlo Park”, he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory. Thomas Edison held a world record of 1093 patents for inventions .

Issac Newton More to Patient Attention


Issac Newton Science Quotes - SciencePivot.com

 

Issac Newton – English physicist and mathematician, and the greatest scientist of his era. Most of his discoveries still influence us in the present.

Quote – If I have ever made any valuable discoveries, it has been owing more to patient attention, than to any other talent.

Newton was accomplished for discovering numerous brilliant scientific and mathematical concepts. Among those discoveries were his theories of motion and gravitation, the components of light and color and his development of the foundations of calculus. “Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.”

Stephen Hawking We Are Advanced Breed of Monkey

Stephen-Hawking-Quotes---SciencePivot

 

Stephen Hawking, English theoretical physicist and cosmologist who is universally considered to be one of the most intelligent scientists alive today. Currently, he is the director of research at the Centre for Theoretical Cosmology, University of Cambridge.

Quote: We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.

Stephen Hawking has explored on the basic laws which govern the universe. With Roger Penrose he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science.

Isaac Asimov – The Most Exciting Phrase in Science

Issac-Asimov-Exciting-Phrase-in-Science- SciencePivot

 

 

Isaac Asimov – Russian-born, American author, professor of biochemistry at Boston University

Quotes – The most exciting phrase to hear in science, the on that heralds the most discoveries, is not “Eureka!” (I found it!) but “That’s funny…”

Isaac Asimov was one of the 20th century’s most prolific author who penned nearly 500 books, he published influential sci-fi works like I, Robot and the Foundation trilogy, as well as books in a variety of other genres.

“If you want to be a prolific writer, you have to be a single-minded, driven, non-stop person. Sounds horrible, doesn’t it? Well, then, concentrate on being a good writer, and leave prolific for those poor souls who can’t help it.”

Mohandas Karamchand Gandhi, India Anti-War Activist

Quote: The Roots of Violence – wealth without work, pleasure without conscience, knowledge without character, commerce without morality, science without humanity, worship without sacrifice, politics without principles.

Mahatma Gandhi was the primary leader of India’s independence movement and also the architect of a form of civil disobedience that would influence the world. Strength does not come from physical capability. It comes from an indomitable will.

Claude Bernard The Joy of Discovery


Claude-Bernard-Science-Quotes_SciencePivot

 

 

Scientist: Claude Bernard, French physiologist.

Quote: The joy of discovery is certainly the liveliest that the mind of man can ever feel.

Major discourse on scientific method: An Introduction to the Study of Experimental Medicine (1865)

Known and Unknown. What makes a scientist important, he states, is how well he or she has penetrated into the unknown. In areas of science where the facts are known to everyone, all scientists are more or less equal—we cannot know who is great. But in the area of science that is still obscure and unknown the great are recognized: “They are marked by ideas which light up phenomena hitherto obscure and carry science forward.”

Isaac Newton’s First Published Scientific Paper

Hi Readers, do you know what Mr.Newton wrote about in his first published scientific paper? Let’s discover his big idea back to February 19, 1671.

The content of his first paper started with: A letter of Mr.Issac Newton, Mathematics Professor in the University of Cambridge; containing his New Theory about Light and Colors: Where Light is declared to be not Similar or Homogeneal, but consisting of difform rays, some of which are more refrangible than others: And Colors are affirmed to be not qualifications of Light, derived from Refractions of natural Bodies, (as ’tis generally believed;) but Original and Connate Properties, which in divers rays are divers: Where several Observations and Experiments are alledged to prove the said Theory.

Wind Power
Published April 2, 2013 by

Wind Power

Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.
Large wind farms consist of hundreds of individual wind turbines which are connected to the electric power transmission network. Offshore wind farms can harness more frequent and powerful winds than are available to land-based installations and have less visual impact on the landscape but construction costs are considerably higher. Furthermore, offshore poses problems when considering accessibility for maintenance issues. Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy surplus electricity produced by small domestic wind turbines.

Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land. The effects on the environment are generally less problematic than those from other power sources. As of 2011, Denmark is generating more than a quarter of its electricity from wind and 83 countries around the world are using wind power on a commercial basis. In 2010 wind energy production was over 2.5% of total worldwide electricity usage, and growing rapidly at more than 25% per annum. The monetary cost per unit of energy produced is similar to the cost for new coal and natural gas installations.

Wind power is very consistent from year to year but has significant variation over shorter time scales. The intermittency of wind seldom creates problems when used to supply up to 20% of total electricity demand,  but as the proportion increases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur. Power management techniques such as having excess capacity storage, geographically distributed turbines, dispatchable backing sources, storage such as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing demand when wind production is low, can greatly mitigate these problems. In addition, weather forecasting permits the electricity network to be readied for the predictable variations in production that occur.
