The Egoist In Me

I'm 44, married, childfree, and I live in Southern California. Foodie, technophile, bibliophile, independent voter, wannabe-deep thinker, amateur gourmet, beer enthusiast, tumblr (re)blogger, and pc gamer. I'm a very sarcastic, cynical, and optimistic person. I work, I go to school, I play computer games, I read, I listen to music. That's my life in a nutshell. Everything else is just decoration.

-We are made of stars. I love the cosmos, therefore I love me.

Physics-exploiting axe splits wood in record time
By Ryan Whitwam
Chopping wood is hard, but it’s something modern society has largely freed us from as a daily activity. That’s nice, but consequently, if you ever do have to chop wood, you’re more than likely going to suck at it. Splitting a log requires a surprising amount of force, but Finnish inventor Heikki Kärnä has invented a new kind of axe that makes it much easier and safer.
Yes, axes have existed since time immemorial, but apparently there’s still room for improvement.
The Vipukirves does what the name implies, assuming you speak Finnish. It’s essentially acting as a lever instead of a wedge (Vipukirves translates as Leveraxe). A regular axe needs to be driven downward with enough force to separate wood along the grain. That’s a lot of force, and if a log is hit off center, the axe blade can deflect at unexpected angles. That’s not good — your squishy flesh is much easier to split than a log.

So what makes a lever different than a wedge in this scenario? The Vipukirves still has a sharpened blade at the end, but it has a projection coming off the side that shifts the center of gravity away from the middle. At the point of impact, the edge is driven into the wood and slows down, but the kinetic energy contained in the 1.9 kilogram axe head continues down and to the side (because of the odd center of gravity). The rotational energy actually pushes the wood apart like a lever. A single strike can open an 8 cm gap in a log, which is more than enough to separate it.
The inventor also claims this tool is much safer because the downward energy that might cause harm is dissipated gradually as rotational energy. So, no abrupt shock, and no deflection. The Vipukirves also naturally comes to rest on its side, which stabilizes the log and keeps the sharp edge pointed away from the operator. It’s really a clever design.

If you want this crazy physics-exploiting axe, it’s going to cost you. The base price is €193.12 in EU countries, including VAT. For US orders, the base price is €155.74 or about $215, plus €47.26 ($65) in shipping.

It’s still National Library Week. You should be especially nice to a librarian today, or tomorrow. Sometime this week, anyway. Probably the librarians would like tea. Or chocolates. Or a reliable source of funding.

URGENT : Last night, we told the IRS: new rules governing dark money need new data to work — and transparency is the only solution. Today is the last day the IRS will accept public comments on a rule proposal that could finally regulate political nonprofits, and stem the flow of dark money in our elections.  Read our proposal, then click HERE to tell the IRS, “I stand with the Center for Responsive Politics in their request for transparency. The IRS has a chance to make clear, fair, and enforceable rules for tax-exempt organizations to stem the flow of dark money in U.S. elections, and allow citizens to access information they deserve: http://bit.ly/1mI8uts.”

Thank you for taking a stand for transparency!
