Sir Isaac Netwotn’s three laws of motion. Three states of matter (solid, liquid, gas). We live on the third rock from the sun. Our metric system of measurement uses metre, litre, and gram. Morse code is a reliable system as the signal is made up of only three parts – a long ‘on’, the dash; a short ‘on’, the dot; and an ‘off’ signal. Do you know what SOS means in Morse code?

Super Blue Blood Moon

Super Blood Moon 2018
Super Blood Moon 2018

The rare Super Blue Blood Moon is about to happen for the first time in 150 years!

Early Wednesday morning brought a lunar event that hasn’t been seen since 1866.

It was at least partially visible in all 50 U.S. states, though the views were better the farther west you live.

Let’s break this down. This event – called a super blue blood moon – was actually three fairly common lunar happenings all happening at the same time.

And scientists say that information gathered during the event could help them figure out where to land a rover on the moon.

How is what3words able to provide accurate address of every location?

With what3words, Chris Sheldrick and his team have divided the entire planet into three-meter squares and assigned each a unique, three-word identifier, like famous.splice.writers or blocks.evenly.breed, giving a precise address to the billions of people worldwide who don’t have one. In this quick talk about a big idea, Sheldrick explains the economic and political implications of giving everyone an accurate address — from building infrastructure to sending aid to disaster zones to delivering hot pizza.

We have named every 3mx3m in the world with unique combination of 3 words.

Geospatial Start up of the Year is valuable recognition for What3Words.

The Idea behind what3words was to use words 3 words as it is easy for people to grasp.

We use latitude and longitude with our algorithm to generate 3 words addressing.

We do not use any address or pass code or anything which is much bigger then 3 meters.

Pythagorean theorem

What do Euclid, 12-year-old Albert Einstein, and American President James A. Garfield have in common?

They all came up with elegant proofs for the famous Pythagorean theorem:

In mathematics, the Pythagorean theorem, also known as Pythagoras’s theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

3 THINGS THAT HAPPEN WHEN YOU STOP SHOWERING FOR A MONTH

  • You won’t actually smell
  • Your skin will moisturize itself
  • You’ll save so much extra time

Ever skip a shower after a workout? Maybe. What about skip a shower for an entire month? That’s what one writer from The Atlantic, James Hamblin, set out to do.

No, it wasn’t out of laziness (although we wouldn’t quite blame him). It was actually an experiment to see whether his natural microbes—found in the gut, as we know, but also on the skin—were enough to keep him smelling clean and fresh, without any extra products. (He did wash his hands regularly, though, and rinsed off when he was visibly dirty, “like after a run when I have to wash gnats off my face, because there is still the matter of society.” Good call.)

In school, rarely do we learn how data become facts, how facts become knowledge, and how knowledge becomes wisdom.

Eclipses

Eclipses, solar and lunar, have fascinated scientists and lay people for centuries. In ancient times, eclipses were seen as phenomena to be feared – many cultures came up with stories and myths to explain the temporary darkening of the Sun or the Moon. In recent centuries, eclipses have been sought after by scientists and astronomers who use the events to study and examine our natural world.

Solar eclipses can only occur during a New Moon when the Moon moves between Earth and the Sun and the 3 celestial bodies form a straight line: Earth–Moon–Sun.

There are between 2 and 5 solar eclipses every year.

There are 3 kinds of solar eclipses: total, partial, and annular. There is also a rare hybrid that is a combination of an annular and a total eclipse.

color blindness

Normal Vision
Normal Vision

There are three main kinds of color blindness, based on photopigment defects in the three different kinds of cones that respond to blue, green, and red light. Red-green color blindness is the most common, followed by blue-yellow color blindness. A complete absence of color vision —total color blindness – is rare.

Deuteranomaly
Deuteranomaly

People with ‘faulty’ trichromatic vision will be colour blind to some extent and are known as anomalous trichromats. In people with this condition all of their three cone types are used to perceive light colours but one type of cone perceives light slightly out of alignment, so that there are three different types of effect produced depending upon which cone type is ‘faulty’.

The different anomalous conditions are protanomaly, which is a reduced sensitivity to red light, deuteranomaly which is a reduced sensitivity to green light and is the most common form of colour blindness and tritanomaly which is a reduced sensitivity to blue light and is extremely rare.

Trichromacy or trichromaticism is the possessing of three independent channels for conveying color information, derived from the three different types of cone cells in the eye. Organisms with trichromacy are called trichromats.

According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.

Most people are trichromats, possessing three types of cone cells to see color with. A woman in northern England has four types of working cone cells, which means she has the ability to see far more colors than most of us can.

The plague

Types of Plague

Plague
Plague

There are three different types of plague: bubonic plague, septicemic plague, and pneumonic plague. The most common type is bubonic plague. Septicemic plague occurs when the Yersinia pestis bacteria (the organism responsible for the disease) multiply in the blood. Pneumonic plague is the most serious of the three types of plague. It occurs when plague bacteria infect the lungs, causing pneumonia.
