When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.
Gaining major consumer support and the ire of Big Cable, Aereo today announced support for the Chromecast through it's Android app. A revolution for cord-cutters, Aereo lets you record and stream live broadcast TV on your computer, smartphone, tablet, or media streaming player (Apple TV, Roku, and now Chromecast).
I love Android, and I think its apps are great—the polish that came with the Ice Cream Sandwich update truly put Android design on the map. That being said, one of the more frequent complaints from iOS fans continues to be that apps just "run smoother" and "look better" on iOS than they do Android.
Android 4.4 KitKat has begun rolling out for the Galaxy Note 3 in India, Poland, Russia, Switzerland, and several other countries, and an unofficial build for AT&T customers has been leaked for all of us stateside.
Improved S Pen functionality materialized in the form of Air Command controls on the Samsung Galaxy Note 3, allowing users to access shortcuts for their stylus features from anywhere on the screen. While the pie-interface controls are extremely useful, the only way to access them is when the S Pen is removed—making it impossible to use otherwise.
While ads certainly pay the bills (thank you guys, we love you), they can also be obtrusive and annoying when it comes to accessing and viewing content (not our advertisers though, they rule).
In this Quick Clip, I'll be showing you how a supercooled soda is transformed into a slushy "slurpee" in under 4 seconds. I was inspired to do this little soda trick by The Super Effect's video on YouTube from a few years ago.
Whether you're pressed against your bedroom window, hidden deep inside your linen closet, or lounging on the rooftop, finding that area of maximum Internet speed around your house is usually just trial and error. And when you finally find the sweet spot, apps like Speedtest.net can help you determine how fast your Wi-Fi or cellular connection is overall on your computer or smartphone, so you know your full capabilities. But, if you want to know exactly how fast your Samsung Galaxy Note 2 is u...
We've all had that awful, sinking feeling when something you've been typing away at is suddenly gone. Maybe you accidentally hit the Back button, lost your internet connection, or your computer crashed, but whatever the reason, losing your work totally sucks. A lot of word processing programs have a built-in auto-save feature to prevent you from losing everything, but most websites and blogs haven't gotten there yet. An extension for Chrome and Firefox called Lazarus: Form Recovery can help y...
When most people think of stained glass, the first thing that comes to mind is a church, but it's become more popular in home decor as well. The biggest downside is that high quality stained glass pieces can be insanely expensive—and it's not an easy project to take on yourself.
Even though it seems like forever, the phenomenon of "rickrolling" has only been around since 2007. It was started as an inside joke by a 19-year-old who just wanted to troll his buddies, but ended up becoming one of the Internet's most popular memes with over 66 million views (as of this writing).
One of the issues most commonly complained about with the Google Nexus 7 is speaker defects. Some people have issues with their tablets freezing when using the built-in speakers, others say they were pretty much busted right out of the box.
I use Google Chrome every day for my browsing needs, and I had no idea they were hiding something from me. So, I was pretty surprised to see that Chrome has an entire hidden experimental add-ons section. There are add-ons that work for Mac, Windows, Linux, and Chrome OS, so there's something for everybody.
In the Windows 8 Enterprise edition, you can use the Windows to Go feature to travel with Windows 8 OS, personal files, documents, settings and many more. All you need is an external hard drive or USB drive of 32 GB space or more and USB 3.0 support or more for fast Windows 8 booting. We need the storage media of above specification to create bootable USB to access the data anytime by plugging the media into different PC running latest version of Windows 8 PRO or Windows 7.
There are tons of ways to make a macro lens for your smartphone, but if you need one for a DSLR, it's not quite as simple as using a magnifying glass or a drop of water. If you have an old kit lens, though, you can turn it into a macro lens in no time—all you have to do is remove the front element. For this hack, Juha Loukola over on PetaPixel used a Canon 38-76mm lens, but says that the process should be pretty much the same for other lenses.
Tired of the Instagram wave? If you're sick of having to view the world through low-contrast and sepia-toned filters, there's a way to get them back to how they're supposed to look, and it's called Normalize, which undoes the magic filtering that Instagram and similar photo filter apps provide. The process of un-Instagramming your (or anyone else's) photos with Normalize is perhaps easier than Instagramming them in the first place. All you need to do is copy and paste them into the app and wa...
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...
It's been a long time coming, but Apple Maps finally has cycling directions for your iPhone. Google Maps has had cycling support for ten years now, though, many of its more useful features had been incorporated within the last few years. Well, with iOS 14, Apple has caught up, and it's done a fantastic job.
When WhatsApp first came out in 2010, it quickly gained notoriety as a great way to meet new people all over the world thanks to group chats, which allow multiple admins for each group that can all add participants from their own contacts lists.
The Shortcuts app can help you play the next unlistened podcast from one of the shows, but getting the latest unplayed episodes from your whole queue of shows in the Podcasts app is a little trickier. There is an easy way to do it on your iPhone, though, and you can even automate it so that Podcasts plays your most recent untouched episode automatically.
For those that have deafness or are hard of hearing, the iPhone can be a powerful tool to communicate with others. It works with many hearing aids and Bluetooth headphones, Live Listen makes it easier to hear nearby people and sounds, and the Messages app makes it easy to chat with anyone. But iOS 14 takes it to a new level, one that even users with perfect hearing can benefit from.
So you're listening to Spotify on your Note 10+ and you pause it for a second to talk to someone. A minute or so passes, and you press the play button on your wireless headphones ... but nothing happens. That's because Samsung already killed the Spotify app. Here's how you can prevent this.
Normally, when you scroll down a webpage in Safari on your iPhone, it automatically hides the bottom toolbar and minimizes the top Smart Search field. But as soon as you scroll back up, they both reappear, which can be pretty annoying if you don't need them. Apple's iOS 13 update brings many new features to Safari, one of which solves the toolbar issue so you can keep it hidden when reading.
Cosmetics augmented reality specialist ModiFace appears to be really benefiting from the brand power of L'Oréal, which acquired the company last year.
New images reveal that Microsoft is already well underway in fulfilling its $480 million contract to provide augmented reality headsets to the US Army.
In MyFitnessPal, you can search through a food database to add your meal into the app's diary and track your calories. Unfortunately, the sheer size of the database can make it hard to find exactly what you have just consumed, which is why MFP includes a barcode feature to make the process of adding food much smoother.
Instagram is no stranger to stealing features from Snapchat. Stories, originally a Snapchat invention, feels more at home with Instagram today. Now, Instagram is attempting to repeat this feat with nametags, a way to quickly add new friends akin to Snapchat's Snapcodes.
There's a fine line between order and chaos in group chats. With all the cross-talk, threads can easily devolve into a random mess that has nothing to do with the original discussion topic. WhatsApp group chats certainly aren't immune to this problem, but they've recently taken a step in the right direction.
It looks like Google's feud with Amazon won't end anytime soon. A war has been brewing ever since Amazon pulled Chromecast, Apple TV, and other competing devices from their store in 2015, but the latest exchange is a huge blow to people using Amazon Fire tablets and streaming TV sticks.
Using the Mail app to log in and sync to email services such as Gmail and Outlook is incredibly easy to accomplish on the iPhone thanks to the intuitive nature of its operating system. This is still evident with iOS 11, and though the process differs slightly from its predecessors, it can still be accomplished with relative ease.
The total solar eclipse is just a few days a way and everyone is buzzing about it. It will be visible in the US from Oregon to South Carolina with 16.5 million people able to view it.
Unlike the iOS App Store, which is a one-stop shop that lets you search for and instantly download apps on your iPhone, jailbreak apps found within Cydia are far more fragmented and not as easy to source. In fact, Cydia only comes stock with a fraction of the apps and tweaks that are available on its official Apple counterpart. That's where Cydia repositories come in.
Heathrow Airport's most recent arrival isn't a flight, but rather an interactive children's game featuring augmented reality technology.
Thanks to a $100 million deal, you could be seeing more original shows on your Snapchat soon. Already, Snap has been producing super short shows in order to compete with social media outlets like Twitter and Facebook who have also been attempting to create their own content. While musical.ly has so far had the biggest success in this area, this deal with Time Warner is certainly promising for the beleaguered platform.
Prepare yourself for a trip back to the days when a Sega Genesis was your gateway to premium gaming. The mid-nineties classic, Comix Zone, has been soft-launched in the Philippines, and while it's not officially available for gamers in the states, you can install it right now with a little hackery.
Thanks to Google's latest update to their Motion Still app, iPhone users can now pick a new frame for Live Photos. The app fixes everything annoying about Apple's Live Photos, and this is just another great feature to add to Motion Still's impressive features list.
In February, the popular Facebook-owned WhatsApp Messenger service jumped on the "stories" bandwagon and replaced their in-app, text-based "About Me" status (you know, those lovely little messages where you can say "Sleeping" or "Not Sleeping" under the tiny nub of your profile picture). Taking its place was a clone of Snapchat's Stories feature, continuing the social media giant's recent trend of shamelessly copying Snapchat.
If your phone has an AMOLED display, it doesn't waste any battery to power black portions of the screen. This is because the individual pixels that make up an AMOLED screen emit their own light, which means the backlight you'd find behind a traditional LCD screen is not present. In other words, showing a full-screen black image on an AMOLED phone is like turning your display completely off.
We've highlighted the projects of Wavelength Studios a few times over recent months for their work in the augmented and mixed reality space. Since receiving their HoloLens headsets, they've been hard at work on both development community projects as well as efforts for clients. This brings us to their latest work—a way to control holograms on the HoloLens with our pocket-based modern miracles, also know as smartphones.
Granola is an excellent anytime food. It's a healthy breakfast, an easy snack, and a delicious dessert. Unfortunately, it can be expensive to buy, and it can take a long time to make. If you're anything like me, you always run out of granola when you need it most.
