Earth's largest recorded impact in history
|
view preview
The Tunguska event was a large explosion that occurred near the Tunguska River, in where is now Russia. The explosion occurred at an altitude of 5–10 kilometres (3–6 mi) by a stony asteroid that is believed to have burst in the air rather than hitting the surface. Since the 1908 explosion, there have been an estimated 1,000 scholarly papers (mainly in Russian) published on the Tunguska explosion. In 2013, a team of researchers led by Victor Kvasnytsya of the National Academy of Sciences of Ukraine published analysis results of micro-samples from a peat bog near the blast epicenter showing fragments that may be of meteoric origin. Estimates of the energy of the blast range from as low as three to as high as 30 megatons of TNT. The energy of th ...

Is Nutella even healthy?
|
view preview
Imagine blending modified palm oil, skim milk powder, cocoa, hazelnuts, and whole lot of sugar – that's how Nutella is technically made. In fact, Nutella contains 10.4 percent of saturated fat and 58% of processed sugar by weight. A two-tablespoon (37-gram) serving of Nutella contains 200 calories, including 99 calories from 11 grams of fat (3.5 g of which are saturated) and 80 calories from 21 grams of sugar. The spread also contains 15 mg of sodium and 2 g of protein per serving. You're probably thinking, what if I gather up these ingredients and do it myself, will I have homemade chocolate spread? Not quite. Nutella uses modified palm oil rather than regular vegetable oil because it remains solid at room temperature. This modified oil i ...

The marble machine features multiple instruments including a bass guitar, cymbals, and a vibraphone all played by falling marbles. Apart from the 11 mm steel ball bearing marbles, he made all the gears powering the machine by hand. ...

Want to relive the 90's? This emulator let's you use Windows 95 on your browser
|
view preview
Anyone who used a PC in the 1990's most likely used one with the most popular operating system of its time, Windows 95. Although it reached EOL (end-of-life) status in 2003, Windows 95 doesn't appear to want to die. It has made appearances on smartphones, handheld devices, and tablets for quite some time now, and people don't seem to be getting enough of it. Thanks to a young programmer, we can now have Windows 95 running in almost any web browser using emscripten, an emulator that converts C++ code to JavaScript in real-time. It requires no downloads, plugins, or any special software. The emulator takes a minute to load up, but once you’re inside it, it’s surprisingly snappy. It provides you with a full Windows 95 operating system and e ...

How one perceives beauty is merely superficial
|
view preview
Beauty may be in the eye of the beholder, but what’s influencing our eye? Scientists reveal that it’s not genetics but life experiences that lead us to find one face more attractive than another. This finding furthers the on-going debate of nature versus nurture. Here's how the study went down: Researchers asked 547 pairs of identical twins and 214 pairs of same-gender fraternal twins to view 200 faces and rate them on a scale of one to seven, with one being the least attractive and seven the most attractive. A group of 660 non-twins then completed the same survey. If genes were more involved in facial preference, identical twins would have had similar ratings; if the influence of a familial environment carried more weight, fraternal twins w ...

What's it like to float on thin air?

view preview
Apparently, walking across this glass pedestrian bridge in Zhangjiajie’s Grand Canyon, China is meant to make you feel like you're floating in thin air. The bridge seems to float 1,300 feet above the ground, almost as though it were part of the clouds. The bridge will be open later on this year!

Humans and Earth - the battle
|
view preview
When you turn on your TV, it is the definition of ironic to watch the news channels for information about planet mass destruction. Whilst when you step outside your door, it is quite alarming and obvious that our earth is suffering. When every person around you, from toddlers to elderly, own some for of technology, with no means of recycling old items. When students, each with their own copies of pages. When potable water has not yet reached the most needy of nations. When human greed is apparent with every innovative idea claiming to "revolutionize "a domain brought up to make a quick buck. Drilling, mining, industrialization, politics, scavenging for resources, suffocating our environment... This may all seem negative, but coming from a ...
