On the internet you find something interesting around every corner. This is me filtering out the noise and collecting gems... And making the world a better place by polluting the internet even more... :D
Hey Tumblr user, please read this text :) I’m a 19 year old Belgian guy and I’ve made an Android app which lets you measure the distance to a lightning and see it on Google Maps. It has a bunch of cool features which you can see in the video above. It would be nice if you would try it out and test the app, it’s free! Get it on Google Play here
If you want to support me, please like/reblog this post, it helps me a lot! (I can’t spend all the money on marketing like big companies do) Thanks :)
Joint popping is one of those things some people revel in and others detest. What you may not have realized, though, is that fluid dynamics are responsible for the sound. Joints contain a non-Newtonian liquid called synovial fluid to lubricate them. When you manipulate the joint to stretch it, pressure in the fluid drops and gases dissolved in the synovial fluid are released, forming a cavitation bubble. The creation and collapse of this bubble are what cause the audible popping. (Video credit: SciShow)
Unconscious biases influence our actions every day, even when—by definition—we don’t notice them. These biases are shaped by our experiences and by cultural norms, and allow us to filter information and make quick decisions. We’ve evolved to trust our guts. But sometimes these mental shortcuts can lead us astray, especially when they cause us to misjudge people.
