The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Early scientists, unable to perceive light's motion, thought it must travel instantaneously. Over time, however, measurements of the motion of these wave-like particles became more and more precise. Thanks to the work of Albert Einstein and others, we now understand light speed to be a theoretical limit: light speed — a constant called "c" — is thought to be not achievable by anything with mass, for reasons explained below. That doesn't stop sci-fi writers, and even some very serious scientists, from imagining alternative theories that would allow for some awfully fast trips around the universe. Speed of light: History of the theory The first known discourse on … [Read more...] about How Fast Does Light Travel?
In a blog post today, Google is announcing that it’s formally embarking on a project to convince the group in charge of web standards to adopt technology inspired by its Accelerated Mobile Pages (AMP) framework. In theory, it would mean that virtually any webpage could gain the same benefits as AMP: near-instantaneous loading, distribution on multiple platforms, and (critically) more prominent placement on Google properties. This sounds impenetrably dense and boring, but please don’t click away yet! This is important, a little tricky to understand, and critical to how the web and Google interact in the future. In many ways, Google’s success or failure in this endeavor will play a major role in shaping how the web works on your phone. If you’re unfamiliar, AMP is Google’s attempt to make webpages as fast and portable as other “instant articles” (like what you might read on Facebook or Apple News). The idea is that when you click a link on those … [Read more...] about Inside Google’s plan to make the whole web as fast as AMP

It’s no news that we’re in the full throes of a digital age marked by big data and analytics, driven by new technologies that have enabled companies to easily and quickly amass massive datasets from a variety of sources. The real dilemma that this data overload has caused is how to make meaningful sense of all that structured and unstructured data. This is where insights-as-a-service comes in. As a new trend, people are defining it in many different ways, but in reality, insights as a service is a process through which an external provider makes sense of data for you. In typical “as a service” fashion, it lets you buy only the insights you need, using your own, as well as supplementary data, and analyzing that data to answer specific business questions.The insights-as-a-service market size is expected to grow from $1.16 billion in 2016 to $3.33 billion by 2021, according to a report from MarketsandMarkets. I believe, however, that it’s only going to … [Read more...] about Insights-as-a-service: Giving companies a fast lane to data-driven action
The Federal Communications Commission's 2015 net neutrality rules will officially be dead in a matter of weeks. So naturally, people are anxious about what that means for the internet as we know it today.It's this anxiety and fear that's likely fueling recent blog posts stating that AT&T is rolling out so-called "internet fast lanes."But is it true? Is AT&T carving out lanes on the internet and offering the speediest service to the highest bidder, while leaving all other internet traffic relegated to "slow lanes"?Not exactly. AT&T hasn't introduced a new service that explicitly prioritizes one type of traffic over another. "The author is getting the two distinctly different concepts mixed up," an AT&T spokesman said by email. But that doesn't mean that it isn't offering other services that might run afoul of the strict net neutrality restrictions that are set to expire next month. CNET has put together this FAQ that explains what's really going on and why consumers … [Read more...] about No, AT&T hasn’t created internet fast lanes. But…
