Women scientists

12 badass scientists(STEM : Science, Technology, Engineering, and Mathematics)

“Everywhere you look, odds appear stacked against women in STEM. Young male scientists receive up to twice as much funding as their female counterparts in Boston’s biomedical research institutions, a global research hub. Only 30% of the world’s researchers are women, and women hold fewer than 25% of STEM jobs in the US. In fact, one recent survey found 67% of Europeans and 93% of Chinese respondents don’t even believe women have the skills to do science — and Nobel Prize-winning biochemist Tim Hunt thinks women cause ‘trouble’ in the lab.

But take a look at the above portrait, which was taken by photographer Bret Hartman at the TED Fellows Retreat in Pacific Grove, California in August 2015. These 12 scientists represent a range of disciplines — from astrophysics, biology, genetics, archaeology, medicine, glaciology, data science and more — and represent 5 countries around the world. They also happen to all be women. And while a portrait like this one shouldn’t be extraordinary in 2015, it sadly is — highlighting a very real, very large gender gap in the sciences.”

Toddler’s head reattached by doctors in medical miracle – YouTube.

This 16 months old baby was in a car crash with his mother and sister. The impact was severe and he suffered internal decapitation: his spine was dislocated, the head separated from the neck (only the bones were separated, the spinal cord inside and the skin and flesh around were still attached).

Pi: 3,14… a magical number put into music

As you might recall from math class, pi is the ratio of a circle’s circumference to its diameter. This irrational number—approximately 3.14159—shows up quite frequently in many mathematical applications, including geometry and trigonometry.

The first attempts to calculate pi can be traced back to ancient Babylonians, who calculated the area of a circle as three times the square of its radius, making the value of pi equal to 3. One Babylonian tablet indicated they got as close as 3.125 and later calculations by the ancient Egyptians (ca. 1650 BC) approximated pi as 3.1605.

The number today is celebrated around the world on March 14, which when written out numerically is 3.14.

On YouTube, Michael Blake decided to pay tribute to Pi. By assigning a number to each musical note, he was able to create a composition by playing out the digits of pi. View the video of his piece below.
