Cool Jobs: The Science of Secrets

Brought to you by Sabina


Chick-a-dee-dee-dee. The chickadee gets its name from its distinctive call. The greater the danger, the more “dees” a chickadee adds to the call’s end.

This is so awesome! This article gave so much detail about everything, and I love that. The message in the beginning of the whole thing really draws you in and makes you wonder what's coming next. Forensic science is awesome! But also, it's about figuring out things through animal sounds. Birds make certain calls, depending on what they want to communicate. Chickadees make a Chick-a-dee-dee-dee sound, and that's where they get their name. Apparently, they can "say" to each other to gang up on a predator, which is quite interesting. Also, they add more "dees' at the end of their call, depending on how bad or scared they are of the predator. For a pygmy owl, a Chickadee added 23 "dees" at the end of their call. That's awesome. I knew about how you can't exactly just erase something forever on a phone. So if you delete something on a digital device, it doesn't erase it for a very very very long time. Which is interesting. It's kind of like on your email how after you delete a message or discard a draft, it gives you the option to undo the discard, which is a perfect example of this. A woman uses the tracking thing on a smartphone to see if people were at the scene of a crime, which is really cool. She also uses text conversations, call, contacts, and more. She specializes in that stuff. Sound really fun! It may not seem like it, but that is actually a really important job. Now, so many people have devices, who knows what they are doing with them. Anyway, I loved this!

This is amazing! I think it's awesome that scientists have figured out what all these animal sounds mean. I wonder if the chickadee always says 23 "dee"s when they see a pygmy owl.
I also think it is really interesting that when you delete something from a phone or computer it's not permanent.
I rate this article an A+.
