In this video, learn how to make your own homemade electroscope. An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body and for static electricity experiments. They are easy to make. This electroscope is made from a binder clip and two sheets of plastic (or overhead transparency film), and scissors.
This educational math video describes the steps necessary to solve an equation involving absolute values. "Absolute value" refers to the magnitude of a quantity and is always expressed as a positive number. You can think of absolute value as the distance a number would be from zero if plotted on a number line. Positive 17 and negative 17 both have the same absolute value because both are 17 units from zero on a number line. Because of this, all absolute value problems have two answers, one wh...
In this video the author shows how to do similarity transformations. He says that similarity transformations are used to draw the similar images at a different location and the k value is most important while doing this kind of transformation. He says that a negative k value tells that the copy of the shape will end at the opposite side of the origin to the original shape. He says that a positive k value tells that the copy will lie on the same side of the origin. Next thing about the k value...
35mm lens adapters cost thousands to buy, hundreds to build, degrade the objective technical quality of your video and make your camcorder an entire magnitude more difficult to use. And they won't make your video magically look like film. Nothing will. On the other hand, by adding selective focusing options to small consumer camcorders, 35mm lens adapters have the potential to produce some absolutely gorgeous images. Watch this video tutorial and learn how to adapt a video camera to a 35mm le...
Calculating probablities can be used to help us make decision. PatrickJMT explains how to calculate probability in an "either A or not A" scenario. The probability of A plus the probability of not A is equal to one. Therefore, the probability of A is equal to one minus the probability of not A ; P(A)= 1 - P(not A). The probability of a major earthquake in San Francisco over a period of time is used as an example. The probablity of an earthquake of a magnitude of 7.5 or greater in San Francisc...

When a rod mounted in a hand drill is dipped into a liquid and rotated, for certain non-Newtonian fluids the liquid will climb the rod - sometimes to quite spectacular heights.
Following the launch of the Magic Leap One earlier this month, the device and the company took a few hits from early reviewers. But it turns out those were just love taps compared to the absolute scorched earth acidic screed penned this weekend by someone well credentialed to dissect Magic Leap One: Oculus Rift creator Palmer Luckey.
Will the predicted apocalyptic date—December 21st, 2012—really be the end of the world? In this ongoing five-part series, we examine what would happen if zombies, nuclear weapons, cyber wars, earthquakes, or aliens actually destroyed our planet—and how you might survive.
No one likes to think about the possibility of natural disasters, but we all know they could happen at any time. Some of us are a little more paranoid than others, but wouldn't it be nice to know that you'd be protected if anything really crazy ever happened? Like the zombie apocalypse?
Following up on a preview of the deal we reported during last week's CES, Dell has officially announced the details around its role as the first company to resell the Meta 2 augmented reality headset.

The long, long, loooong wait finally ended this week for the augmented reality community as the Magic Leap One was finally released. The Florida-based company has loomed over the industry for years promising something big, and now the AR cat is finally out of the bag. Now we get to see if it will live up to expectations, but early reviews are a bit skeptical.
A new study shows the Zika virus is present in saliva — but it may not be enough to make you sick. The Centers for Disease Control and Prevention notes there is "no evidence that Zika can be transmitted through saliva during deep kissing." Given the results of research published in the journal, Nature Communications," the agency may need to revise its guidance.
The latest video game developer to hit the scene is a hotel chain, and they're offering big prizes for high-scorers.
This week in Market Reality, we see two companies capitalizing on technologies that contribute to augmented reality platforms. In addition, industry mainstays Vuzix and DAQRI have business news of their own to report.
Computer system authentication is critical to keeping systems safe from unwanted users, intruders, and abusers. Basically, authentication is the process of the potential user proving they are an authorized user.
Over the years, mobile gaming has become a phenomenon, rivaling in magnitude with its console and PC-based counterparts. We even have mobile versions of Fortnite and PUBG now, games that require lots of processing power to run.

Dr. Chester Keefer of Boston was responsible for rationing the new miracle drug, penicillin.
A group of researchers from Stanford University and Princeton University has put together the largest RGB-D video dataset to date with over 1,500 scans of over 700 different locations across the world, for a total of 2.5 million views.
Next to Apple, Snap is currently one of the most important companies on the planet in terms of delivering products that are moving augmented reality into the mainstream. That's why it's no surprise that Facebook, which is also focused on AR and tried to acquire the company for $3 billion several years ago, duplicates many of the smaller company's features.
The future of forests looks dreary in the face of a warming climate, but scientists are exploring the relationship between soil microbes and the ability of trees to move to higher altitudes, a key component of their survival.
Google's former Self-Driving Car project, now graduated from Alphabet's X division as Waymo, has found a collaborator and potential new partner in Honda. This is an interesting turn of events given traditional automakers' reluctance to work with driverless-car startups over the years.
The development of virtual reality at Facebook has been evolving lightspeed in the last few years. But while a relatively small group of VR enthusiasts and gamers are enjoying the social media giant's dedication to immersive headsets, it is the augmented reality space and its potential scale that truly has the tech market enthralled.
The mission to rise above the fray to become a leading player in the augmented reality business is a moving target that depends on innovation, resources, and timing.

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...

Wow, what can't Google do? Check out the winter Olympics, ride the Trans-Siberian railway, explore the world's largest airplane graveyard, and now, locate Chilean earthquake victims.
There is a ton of evidence that people find a loss from whatever their reference point is more painful than they find pleasure in a gain of the same magnitude.
The comet Garradd is almost at its peak now, plus there's plenty more events going on this week, so be sure to observe!
Grab your binoculars and telescopes, because there's a lot going on in the night skies this week.
