BuzzFeed: 7 tricks to do in regards to your camera


BuzzFeed, seo pun intended here, does not always have a great list or a great video, but from time to time they do get something right, like in the video from above. The string tripod, the cup tripod or how to build a light box are a couple of things I didn’t thought about doing, but they are good to know.

At the eshop I’m working, Reeija, we had a hard time finding a good photographer and for a while we wanted to buy or build our own light box. Didn’t occurred to us that it was that easy t do it. For this BuzzFeed has my props 😀

It’s not the speed that kills ya, it’s the speed difference


It is not the speed, not the speed, but the speed difference that makes the kill. I didn’t knew that the speed limit was set in regards to oil consumption and not to safety concerns. That makes me a bit angry.

In any case, having fast lanes and highways is a big need and raising the speed limit should be allowed in many places. Now that I know that not the actual speed is the issue, more the speed difference and the driver not paying attention to the road, I might look at driving in a whole different way.

Awesome Onewheel Electric Skateboard


OneWheel is a great travelling companion. It works much like a segway, but with one wheel. It has a small gyro and a motor that can get you to a 7 miles long evening travel. The battery loads in about 4 hours and it costs $1500 if you preorder now.

While it is not cheap[, if you have some spare cash and want to spend it on something cool, then OneWheel is a great way to do that. Gotta get one for me sometimes 😀

Coriolis effect explained as simple as possible


The Coriolis Effect is not an actual force, but an apparent one. It is an effect that can be seen in only at large scales, like hurricanes, but not in your toilet, when you flush it.

The Coriolis Effect is generated by the fact that Earth rotates and if you were to throw a ball far enough (over 3-5 miles) then you would see that the given ball is having a curved trajectory, not a straight one, as you’d expect.

If you’re in the Northern Hemisphere, then you can see that hurricanes rotate to the right and on the Southern Hemisphere they rotate to the left. Surprise: at the equator there are not hurricanes.

Minute Physics: is the Universe only Math


Wherever physicists look at the Universe they see the physical laws that govern it and the math that can be used to describe it falls in perfectly. This is why, if you can explain so many things with math, people are asking them selves if the Universe is indeed math.

If you ask me, I’d say no. Math is only part of what the Universe is. Our psychology cannot be encompassed into mathematical equations, for example. In any case, Max Tegmark has written Our Mathematical Universe: My Quest for the Ultimate Nature of Reality (affil link) and this book sends us to the mathematics behind our Universe. I’ve started relearning math and physics. Many things make sense if you learn a bit more math and physics.

Sexy math


This is what we needed in high school: a cute lady that loves math to also make us love math. Hannah Fry explains the importance of algebra in explaining the phenomenon around us and why using letters like “X” gives us enough flexibility to encompass many answers to out questions. Using letters in algebra lets you plot through a graph or gain more insights on some vectors (speed or acceleration by time or distance for example).

In any case, math is great and Hannah surely crushes some hearts wherever she goes 😀

Using birds to fish [clever]


On Li River, in Guangxi province of China, there is another kind of fishenmer: they use birds like Cormorants to catch fish. Those birs can swim pretty fast and they catch the prey in no time. To prevent those birds to eat up the fish the fishermen tie a know around the birds neck, but not too tight.

After the work is done the Cormorants receive their pay in a couple of small fish. Nice way of fishing, that is sure 😀

Dimetrodon is NOT a dinosaur


News flash: some ancient animals are NOT dinosaurs. Dimetrodons, those mammal-like reptilians that lived with 60 million years before the dinosaurs are such examples. They look like reptilians with big crest on their back.

From the video in this blog post you will learn about the fact that we and the reptilians have a common ancestor and that we and the Dimetrodons, which were synapsids, like we are, have another common ancestor. Evolution is crazy and I’m glad that the scientists took the time to properly classify all the animals they could find.

BTW ancient animals mean animals that have only few steps of evolution throughout the millions of years.

Some illusions for za week-end


Having a crazy time right now. with 2 jobs and some side projects I don’t really get to even sleep as much. Ok, I admit, one of the jobs is blogging as I write on three blogs: obisnuit.eu, tehgeektive.com and tehnocultura.ro. Sometimes it can be too much with 5-10 blog posts a day so, I’ll take a leave of absence now and then.

Have fun with the above illusions. Most explanations revolve around the fact that the brain does not really understand what happens in certain situations and then tries to build it’s own version of reality. Even though the eyes see what they should, the brain rewires the information so that it will show us another world. Neat, eh?

Timelapse: supercell formation


The Wright to Newcastle, WY Supercell Time-Lapse was created by Wheather Adventures and features a storm forming a supercell. The crew roams around the supercell and cathes the most intriguing developments of the clouds and their strange behavior. Gladly, no one was hurt and they created a video that gathered over 10 million views. Now that’s a superstorm of views.
