A new Lumia phone from Nokia, this year’s Google I/O and BlackBerry World — yep, it was a pretty hectic week for us, but also a good seven days for tech news. Even if Google didn’t have any truly new hardware for us, it’s started up its own on-demand music service, gave us more details on Google Glass, redesigned its Maps and, well, it was a very long keynote. Join us after the break for a numerical breakdown of that and the rest of the week’s big news.

Welcome to The After Math, where we attempt to summarize this week’s tech news through numbers, decimal places and percentages.

This week’s After Math appears to have taken on a comic book theme. Want to make your own Thor hammer? How about your very own Atomic Watch — rather than those radio-wave-based excuses of a timepiece? We’ve also got the very real prospect of civilian flights to outer space and, er, Kobe Bryant advertising Lenovo smartphones. Stranger things have happened, right? Join us after the break.

Welcome to The After Math, where we attempt to summarize this week’s tech news through numbers, decimal places and percentages

We’ve been getting our first unfiltered experiences with Google Glass this week, which makes it the perfect time to go over some of the salient points up until now. At the same time, Apple sold more hardware, more apps and made even more money — it was largely another good quarter for the Cupertino coffers. Add in a million-second game show and there are more than enough numbers to play around with in this week’s After Math.

Welcome to The After Mathematics, where we try to summarize this week’s tech news with numbers, decimal places and percentages

In a bid to nicely conclude this week’s occasions, we gaze at some expensive 4K gear at NAB 2013, identify whether we can physically … pocket either of Samsung’s Galaxy Huge variants and think about lasers: sometimes stunning, occasionally harmful and in some cases battling the future battle against drones. We’ve got the numbers– and a few dollar signs– right after the break.

Welcome to The After Math, where we attempt to summarize this week’s tech news through numbers, decimal places and percentages.

Barcelona’s Mobile World Congress may have formed the backbone for this week’s news but there was also notable news elsewhere — like the fact that Boston Dynamics’ upgraded quadruped robot can now throw cinder blocks. We’ll be sticking closer to the (safer) events in Spain, however, so take a look for yourself after the break.

I was never good at math and I’m still not now. 5 x 5 = 30. Okay that time I actually got it right, usually I do not though. And now researchers have actually uncovered that anxiety about doing mathematics causes a mind response just like one when experiencing bodily damage. DO YOU HEAR THAT, MS. McKINLEY? You were eliminating me the whole time!

” For someone who has math stress and anxiety, the anticipation of doing mathematics propels a comparable mind reaction as when they experience pain– say, burning one’s hand on a hot cooktop,” said Sian Beilock, professor of psychology at the University of Chicago and a leading specialist on math anxiousness.

Remarkably, the specialists located it was the anticipation of having to do math, and not in fact doing mathematics itself, that appeared like discomfort in the mind. “The mind activation does not happen throughout mathematics performance, suggesting that it is not the mathematics itself that harms; rather the anticipation of mathematics is unpleasant …”

Pay attention: I find the anticipation of doing math and the actual DOING of math equally distressing. To me it resembles having your head in a vice and pounding your fingers in an auto door over and over and over. While on fire. And being eaten alive by tigers. No– ants. It’s like that, but way even worse and a lot more unpleasant.

Thanks to Essi, who’s mind has a similar feedback to doing ANY kind of work. Exact same here!

Ever consulted a crowdsourced review for a product or service before committing your hard-earned funds to the cause? Have you wondered how legit the opinions you read really are? Well, it seems that help is on the way to uncover paid opinion spamming and KIRF reviews. Researchers at the University of Illinois at Chicago have released detailed calculations in the report Spotting Fake Reviewer Groups in Consumer Reviews — an effort aided by a Google Faculty Research Award. Exactly how does this work, you ask? Using the GSRank (Group Spam Rank) algorithm, behaviors of both individuals and a group as a whole are used to gather data on the suspected spammers.

Factors such as content similarity, reviewing products early (to be most effective), ratio of the group size to total reviewers and the number of products the group has been in cahoots on are a few bits of data that go into the analysis. The report states, “Experimental results showed that GSRank significantly outperformed the state-of-the-art supervised classification, regression, and learning to rank algorithms.” Here’s to hoping this research gets wrapped into a nice software application, but for now, review mods may want to brush up on their advanced math skills. If you’re the curious about the full explanation, hit the source link for the full-text PDF.

Question by Rasco 4: What kind of math is required to be a robotics engineer?

Best answer:

Answer by bbullough
There are several engineering disciplines that go into designing and building a robot. A robot is a machine or many machines that are working together and programmed and connected to do one or many actions by themselves. The reason there are fewer factory jobs now that there were years ago is because factories use many robots. None of them look like a robot in movies. You might already know this, but it seems that many do not, so I start with these basics.

That said, “robotics” engineers are a team of engineers, including instrumentation and controls engineers (they may have other terms used in some companies and industries – and there are very few colleges that have a I&C engineering program, so they tend to be electronics/electrical or chemical engineers), machine design engineers, and if the “robot” is doing something in a chemical manufacturing plant, chemical engineers. The specific math needs vary by the role of the engineer, but it order to get any of the degrees (electrical, mechanical, chemical, I&C, or others), all require a year of calculus, about a year (or more) of courses beyond calc I (courses like matrix analysis, differential equations, maybe partial differential equations). I have been involved in many automation projects, including as fully automated as we could reasonably make them, and have used math extensively, and I am a chemical process engineer, not the I&C engineer.

The MPAA is fond of throwing out numbers that show just how damaging copyright theft is to the US economy. Stealing content costs more than $ 58 billion annually, for instance, and robs 373,000 Americans of jobs. With his tongue planted firmly in his cheek, Rhapsody founder Robert Reid used a new technique called Copyright Math to reveal just how massive these numbers actually are. For example, $ 58 billion equals the total output of some of the country’s biggest crops. “This is the equivalent to the entire American corn crop failing, along with all of our fruit crops,” Reid explained during a recent TED talk. “As well as wheat, tobacco, rice, sorghum — whatever sorghum is.”

Oh, but it gets worse. With the music industry seeking damages…

Well…I can cross robotics out of my interests T_T I fail at math so much I still have to use my fingers to count and I’m 18!!! like 9+6 I have to use my fingers T_T
