The cell phone has come a long way. The very first "mobile devices" were made and used by the military in the late 1930s, with the first commercial mobile telephone service introduced by Bell in 1946. These devices were hardly what we'd call mobile today—some took up the whole trunk of a car, and others had to be carried on your back in a heavy bag.

Whether you're an audiophile or just a basshead (cf. Lady Tigra & Bunny), you're certain to appreciate this video, which details how to install passive crossover mid drivers in a car's stereo system. The individual steps are as follows:
This is a great instructional video on how to calculate the age of Universe from Hubble's constant. The speed the galaxy moves away from us is directly proportional to the distance from us. Now think of big bang theory. Hubble's constant is equal to velocity over distance. 1 over Hubble's constant is equal to distance over velocity that is equal to time. Time equals to 1over 71. If you change it into all the same units words it is one over 71000 or 3.09x 10 to the power of 22. It is 3.09x10 t...
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...

Apple's Calculator app received a massive redesign, making it so much more than a simple calculator with built-in scientific functions. There's a new Math Notes feature that ties in with the Notes app, it can keep a history of your calculations, and you can even convert over 200 currency and measurement units.
We've seen a variety of AR experiences related to athletic footwear over the years, but Puma is betting sneakerheads will buy into a version of interactive design where sneakers are the augmented reality experience
This year will be an interesting one for iPhones. With speculation that the expensive iPhone X is underperforming, rumors have circulated that Apple will release three "bezel-less" devices, one of which will cost less by omitting the OLED panel for a traditional, yet large, 6.1" LCD. Now, thanks to the source of this rumor, we have an idea how much that lower-tier iPhone will cost.
The incidence of tuberculosis (TB) is dropping in the US, but the World Health Organization (WHO) considers it to be epidemic in the rest of the world — there were over 10 million new cases in 2016.
Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable.
Several recent research studies have pointed to the importance of the microbes that live in our gut to many aspects of our health. A recent finding shows how bacteria that penetrate the mucus lining of the colon could play a significant role in diabetes.
Amazon's first venture into the wireless phone market was a crash and burn moment — and that's us being kind. Their FirePhone went down in flames almost instantly, no pun intended.
How can bacteria that lives in the throat of 10%–35% of people—without causing an infection—cause life-threatening meningitis and sepsis in others?

Empea Berlin, a Germany-based company specializing in augmented, mixed, and virtual reality software, released a Facebook video a few months back showing off their experiments in smart home technology. Using a Raspberry Pi and a HoloLens unit, they were able to make a virtual remote control for an air conditioning unit. The remote is complete with various modes, temperature controls, timers, and other features. There have been no updates on this project since they first showed it off, but hop...
The Note7 fireworks bonanza was unprecedented in scope. A recent report suggests that Samsung could lose upwards of $20 billion in lost profit due to this fiasco.
Our brains do a magnificent amount of work to process visual stimuli, but they aren't difficult to fool. Optical illusions can trick our minds into believing what we're seeing is real, even if it's not—and virtual and mixed reality technologies take advantage of this little loophole in our brain to help us accept the unreal.
Garlic isn't just a food, it's a legend. It's been found in the pyramids of Egypt and is referenced in the Bible. Hippocrates, the father of Western medicine, prescribed it regularly, and it was given to the first Olympic athletes in Ancient Greece to enhance performance (take that, Lance Armstrong). And, of course, it's famed for its ability to ward off evil, whether it's in the form of vampires, demons, or werewolves.
If you're anything like me, your day doesn't start until you've sloughed away your grogginess with a scalding hot shower.

However, a cold shower can do even more for you if you can stand the low temperatures.
"Ahoy-hoy." If telephone titan Alexander Graham Bell had his way, we'd all be answering phones like Mr. Burns. Thankfully, frienemy Thomas Edison had enough sense to realize we weren't always on the briny. He preferred "hello" as our standard telephone greeting, which he is credited with coining in 1877. Fellow American pioneer Davy Crockett actually used it as a greeting first in 1833 (as compared to an exclamation)—but in print, not over the phone.
For most people, the battery life on a DSLR is more than sufficient, but if you want to do a really long exposure or time-lapse, one charge might not last long enough to get the shot you want. You can always connect it to an extension cord to charge while you shoot, but that can be really annoying to work around.

Not all of us were born with Covergirl skin. In fact, we can bet that even most Covergirls (that's right Drew, even you) weren't born with perfect, front over skin. While we can use products that help exfoliate away dead skin cells and create a brighter glow, sometimes our skin just looks blah.

This is actually quite amazing. If you own an HTC DROID ERIS cell phone, then that cardboard container it came in can be turned into that tiny, but terrific Google Android Bot. The Android Bot logo is known across the world now, and it's odd that their box can be broken down perfectly to recreate it. Was this on purpose, or accident? Anyway, Nextraker found the secret, and he's going to show you how it's down. With just a few basic cuts, you too can have your own little green Bot.
