Ten fun facts about Pierre Simon de Laplace
Fact 1
Pierre-Simon, marquis de Laplace was born on 23 March 1749 in Normandy and died on 5 March 1827.

Fact 2
He recapped and protracted the work of his forerunners in his 5 volume Mécanique Céleste (Celestial Mechanics). This work interpreted the geometric study of classical mechanics to one built on calculus, starting up a wider range of problems.

Fact 3
In statistics, Laplace developed the Bayesian interpretation of probability.

Fact 4
Laplace devised Laplace's equation and established the Laplace transform that is used in many branches of mathematical physics, a field that he took a chief role in founding.

Fact 5
The Laplacian differential operator that is named after him is widely used in mathematics.

Fact 6
He reaffirmed and established the nebular hypothesis as the basis of the solar system and was one of the first scientists to hypothesize the presence of black holes and the concept of gravitational collapse.

Fact 7
Laplace is recalled as one of the supreme scientists of all time. Sometimes mentioned as the French Newton or Newton of France, he owned an extraordinary natural mathematical faculty higher to that of any of his colleagues.

Fact 8
In 1806, Laplace was made a count of the First French Empire and was also named a marquis in 1817, after the Bourbon Restoration.

Fact 9
The asteroid 4628 Laplace is named after him.

Fact 10
Laplace is one of the only 72 people to have their name engraved on the Eiffel Tower.

Ten fun facts about The Mentalist
Fact 1
The show follows former “psychic” Patrick Jane (Simon Baker), who is a consultant to the California Bureau of Investigation (CBI), using the highly developed observational skills he previously employed to “read” people's minds.

Fact 2
The show often sets episodes in fictional locales with names like Salinger Mill and Rancho Rosa.

Fact 3
Like the majority of American television shows, The Mentalist is mostly filmed within the studio zone in Los Angeles County, but occasionally films a few scenes on location in Sacramento.

Fact 4
The structure used to represent the CBI headquarters in Sacramento is the back of the Pico House in downtown Los Angeles.

Fact 5
The pilot episode had an audience of 15.6 million viewers in its first airing, and 7.8 million in a re-airing three days later.

Fact 6
The Dec. 2, 2008 episode, "Flame Red", was the highest-rated television show of the week, marking the first time a program in its first season had achieved that distinction since Desperate Housewives four years earlier.

Fact 7
On Jan. 7, 2009, the show won the award for "Favorite New TV Drama" at the 35th People's Choice Awards. Actor Simon Barker also received several nominations for his role.

Fact 8
On Aug. 21, 2010, The Mentalist was honored with an award for its scientific and critical thinking content, from The IIG during its 10th Anniversary Gala.

Fact 9
Red John is a serial killer on “The Mentalist”. He has long existed before the killings of Patrick Jane's wife and daughter; he'd killed others in Nevada, Mexico and California.

Fact 10
Oliver Tanner was Red John's partner. Red John knew Tanner had a son. He later used him to help him with another murder of a female.

Ten fun facts about Moose
Fact 1
Moose are native to North America but can be found in Europe as well as Asia.

Fact 2
They have hairy skin called bell that hangs under the throat. They have a hump and their front legs are longer than their hind legs.

Fact 3
The sound made by Moose is called a bugle or a bark.

Fact 4
The largest species of the deer family, Moose can grow to a height of 0.8 meters to 1.5 meters. Moose weigh an average of 250 kg to 450 kg. Their lifespan is from 15 to 25 years.

Fact 5
Moose have elaborate antlers that can range between 1.1 meters to 1.4 meters. The male antler is 10% larger than that of the female.

Fact 6
They can run at a speed of 35 mph and swim at a speed of 6 mph. They can stay underwater for about 30 seconds.

Fact 7
Moose have weak eyesight though their senses of smell and hearing are strong.

Fact 8
The females are called cows and the babies are also referred to as calves. Males are called Bulls. The collective name for a group is a herd or gang.

Fact 9
Moose are usually solitary animals but gather in high densities for the breeding season. Only 25% of the groups will have more than two adults.

Fact 10
Herds are typically dominated by one female. The average size of a litter is one to two.

What is the difference between day and night?
What is the difference between day and night? The day starts at sunrise and ends when the sun sets. For people living in temperate climates, the day typically lasts around 12 hours. In this time, we experience a fairly consistent amount of light throughout the day. There are variations depending on where you live, but for most places with an average annual temperature of 10 degrees Celsius, there should be around 8 hours of daylight on a clear day, with 6 hours of darkness during the night.

How does day and night affect the earth?
The earth revolves around the sun, with 365 days/5.8 years in a solar year and 24 hours in a day. At any given time, there are 180 degrees of daylight and 360 degrees of night time. The earth rotates once on its axis every 23 hours and 56 minutes which is the equivalent of one full day for each side of the planet. The earth’s day and night are around 24 hours long.

The length of a day varies based on the tilt of the earth and it changes with the seasons as well. The shortest day is around 6 hours and 40 minutes long, while the longest is around 4 days. That means that we spend 2/3 of our time in sunlight.

Day vs. Night: What changes with time?
When an animal has a short day-night cycle, it is said that the animal experiences a kind of natural jet lag. When an animal has a long day-night cycle, it is said that the animal experiences seasonal affective disorder (SAD). One thing that does not change with time is Earth’s rotation. We all know that night always follows day, but what about the rest of the natural changes in nature? For example, birds return from their flights at dusk and bats set out at dawn.

How do people celebrate a new day and how long is a cycle of a year?

Scientists have found that the calendar is made up of 365 days and a year has an average cycle of 365.25 days. The year is 365 days in length and is divided into four seasons. On the winter solstice, there are 12 hours of sunlight. The longest day has a duration of 16 hours. The shortest day ends in darkness at 3:00 PM EST on December 21st.

The day and night cycles have been happening without interruption for millions of years. If we look at a year as 365.25 days, every night is equivalent to 12 of those days. When the sun sets, it is time to rest while the day begins and it will happen at the same time every morning.

Lightning generates from inside the cold regions of a cloud.
Inside each cloud is an ice cold part around -15°C to -25°C, which causes much of the water in the clouds to turn into tiny ice crystals. The powerful updrafts of high altitudes blow these crystals upwards, along with small droplets of liquid water. As these particles bounce around and against each other, they each gain a small static charge which adds up between them.

Typically, the upper part of a cloud will gain a positive charge, while the middle and lower parts of a cloud gain a negative charge. While the actual process remains unclear, lightning erupts once the charge becomes too much. The excess static crosses over from one side to the other as lightning, neutralizing itself in the process.

Scientists still aren’t sure about what draws lightning to the ground.
All they know is that channels of ionized air called ‘leaders’ slowly descend from the clouds to the Earth’s surface. Forming step-like formations of ionized air as they descend, these channels occur in different levels.

When lightning strikes downward, they follow these channels, which gives lightning its distinctive arcing pattern instead of a straight line. How’s that for intriguing lightning facts?

Lightning does not have heat.
When lightning comes down, it heats up the air it passes through up to 50,000 Kelvin, which makes it hotter than the Sun’s surface at 5,778 Kelvin. The heat of the air also gives lightning its bright and distinctive blue-white color, with the human eye perceiving that heat as colored light.

Despite reacting with the air, lightning itself does not possess an innate heat. With each lightning strike, the air around it cools in a matter of milliseconds.
