Ask a child how to travel through time and you’ll get a simple answer: Use a time machine

Ask a physicist, and suddenly you’ll start hearing outlandish, seemingly made-up terms like “quark” and “quantum gravity.” In that moment, you’ll realize the world of modern physics waved goodbye to simple Newtonian phraseology — the likes of inertia, momentum and plain-old gravity — long ago

So whether you’re trying to erase a mistake in your past, or simply make it through a sci-fi flick without your head exploding, you’re going to need a little more than your dusty high-school physics textbook. Read more…

Tweets can often spark private conversations on Twitter, though the way to do it wasn’t always convenient or obvious (and sometimes involved tedious copying and pasting). Now Twitter is streamlining the process.

Twitter is introducing a new button that lets you instantly share a tweet via direct message.

Twitter announced the new Message button as a simpler way to privately share tweets on iOS and Android. Previously, users had to tap and hold a tweet to pop up a menu and then select “Share via Direct Message” — an extra step that many people probably don’t know about or think about when perusing their feeds.

Imagine you went to your basement and dusted off the laptop or mobile phone that you used in 2002. What would happen if you tried to turn it on? We don’t have to guess. Around the country this election year, people are going into storage, pulling out computers that date back to 2002 and asking us to vote on them.

Following an election meltdown of epic proportions in 2000, the federal government provided more than $2 billion to update the nation’s voting infrastructure. More than a decade later, these voting machines are approaching the end of their expected lifespans. Experts estimate that a reasonable lifespan for electronic voting machines (which are computers, running mainly on laptop technology developed in the 1990s) is in the 10- to 15-year range.

Dubai has gained a reputation as both a center for wealth and excess as well as a city where even relatively minor illegal acts can have major consequences. Now one component of the city’s enforcement efforts will be backed by the latest technology in remote-controlled technology: drones

The Dubai Municipality’s Waste Management Department plans to deploy an entire fleet of drones to police the city’s litterers

Currently, just one drone is operation, but two additional drones will be added later this year. The drones will monitor waste dump sites, beaches and desert camp sites for sanitation law violators Read more…

Selfie lovers, take notice: Chinese phone manufacturer Oppo has a new device out, and it has a 16-megapixel front camera. 

The Oppo F1 Plus, as it’s called, was launched Tuesday at an event in New Delhi. A 5.5-incher with a metal unibody and very thin bezels, it looks like the iPhone and a Samsung Galaxy device had a baby, and we’re guessing most potential buyers won’t mind.

It also looks really good on the specs front, with an octa-core MediaTek Helio P10 processor, 4GB of RAM, 64GB of storage (it can be expanded with an additional 128GB via memory cards), a full HD screen, a fingerprint sensor and a 2,850mAh battery.  Read more…

For years Panasonic’s GH4 has been the go-to consumer camera to record high-quality 4K video. But with an MSRP of $1,500 for the camera body, it’s still more than what many people are willing to spend.

Alongside the G7 and GX8 launched last year, Panasonic’s got another more affordable 4K-capable Micro Four Thirds camera: the GX85. At $799.99 for the camera body, the GX85 is a little over half as much as the GH4.

The GX85 is a 16-megapixel camera and is capable of 8 frames per second (fps) with single autofocus and 6 fps with continuous autofocus. The camera autofocuses in 0.07 seconds and has a maximum ISO of 25,600 for low-light shooting. Read more…
