You Asked How are batteries made? — Kate, Swampscott, Mass. Marshall Answered It depends on the type of batteries. Here is the process of making an alkaline battery: The following video describes the construction of a deep-cycle battery for something like a forklift: And then there is the lithium ion battery: For more info see: [...]
Today I brought in my “Michael Jackson Number Ones” to pay tribute to the King of Pop. While most of the catchy songs are also helping me get into vacation mindset, there’s one track on the disc that’s more likely to induce a severe case of eco-anxiety than the insatiable urge to dance.
That would be “Earth Song,” Jackson’s 1995 environmental anthem, released years before there really was such a thing. Sure, there are earlier environmental songs like “Big Yellow Taxi” and “Mercy Mercy Me (The Ecology),” but “Earth Song” holds nothing back. It has soaring choirs, crucifixion themes and a video with post-apocalyptic rainforests and dead elephants.
I was surprised to learn in the Guardian’s environment blog that “Earth Song” was also Jackson’s biggest-selling single in the United Kingdom. Yes, it beat out other hits like “Thriller” and “Billie Jean” by selling more than a million copies and topping the ’95 Christmas charts.
You Asked Why can’t we see all the debris and satellites that are hovering around above Earth? — Chris, Fairfax, Va. Marshall Answered Let’s start by recognizing that there is one satellite that everyone can see most nights: the moon. And there is one other satellite that is visible to most people if they know [...]
No doubt about it, Ben and I have been pretty busy over the past seven days. However, we both like to take a little time away from our other assignments at HowStuffWorks.com to record a couple of podcasts each week on iTunes. So, what did we talk about?
You Asked Why does my home satellite receiver have to face a specific direction? — Kate, Oakland, Md. Marshall Answered It’s because the satellite that is sending the signal to your house is located at a specific point in the sky. If you could take a powerful telescope and point it in the direction that [...]
I just can’t do it. I can’t not write about the death of Michael Jackson. It’s too big of a deal. I don’t even like the guy’s music anymore, at least not the stuff he released from the late ’80s on. I did worship him for several years, during the Thriller stage.
TechStuff Podcast Roundup: Wolfram Alpha and Tech Flops
by Jonathan Strickland | June 26, 2009
Hey there! It’s time to catch up on what we’ve talked about on TechStuff this week. But before we get into that, I have a tiny announcement to make. I’ll be on vacation next week. What’s more, I’ll have virtually no access to the Internet during that time. I am both exhilerated and frightened by this prospect. Hold me.
I hope that wasn’t too uncomfortable for you. At any rate, Chris and I have recorded some episodes of TechStuff in advance. You’ll still be able to get your weekly dose of TechStuff. On top of that, Chris will continue to blog while I’m away. If you ask him nicely, he may even summarize our next two episodes in a roundup next Friday.
Now let’s get to our topics for this week. On Monday, Chris held court as we talked about Wolfram|Alpha. Chris wrote a great article for HowStuffWorks.com about this computational engine. We talk about the technology behind the engine, reasons why you may want to use Wolfram|Alpha and how other companies like Google are responding to the new kid on the block.
NPR has a crowdsourcing project on their web site. What they are trying to do is identify the people at a senate health care hearing. They have posted photographs of everyone attending the hearing, and they are asking people to help identify who they are: Turning The Camera Around: Health Care Stakeholders TPM has labeled [...]
