edit: Steve Mould's video "I Made a Lens, But for Sound" demonstrates how balloons filled with gasses of different density than the surrounding air, act as a lens on sound waves. Helium filled balloons will scatter sound because the helium is less dense than air. He shows how a balloon filled with carbon dioxide can focus the sound.

- 2007(7th): The mosquito ring tone was a popular notification ring tone. I recall a friend testing it with my math teacher during class. He could not hear it.
- 2010(10th): The last time I recall passing notes in class... I got caught. Apologies to my Geometry teacher. He was one of the best teachers I had.
- 2012(12th): I(late to the party) bought my first phone... The only time I recalll using my phone was when went to the bathroom and accidently dropped it in in the toilet. :'( ... 3 days in a bag of rice and it worked just fine. I'm sure I must have used it in the toilet too many times for that to have happened, but I don't recall ever using it in class, as the punishment was confiscation of the phone and it wouldn't be returned until a parent signed off in person.
The YouTube channel, 'The Quantified Scientist', does a great job of comparing sleep tracking wearables to a reference EEG. He collects a lot of data and presents it very well.
in the spirit of fun, we might set up a system that could deny access if
- more than one person present
- gps location matches known government building
- if law enforcement officers have recently been spotted at a residence or office
- biometrics sense elevated blood pressure/heart rate or other signs of duress
On Android, I disabled the YouTube app and use Firefox for YouTube, entirely because of the shorts. It lets you remove the shorts for 30 days in the browser. I did have to switch text messaging apps because the default option wouldn't work without YouTube enabled whenever someone sent a YouTube link.
I had an issue with my payment for premium which resulted in temporary suspension of my service. A few days after fixing the payment issue, this news came out.
Considering this with the recent price increase, and some trouble with my family plan, my initial reaction was quite negative towards YouTube. They are setting a very clear trend against what I want in their service with recent changes (Removing downvote, removing android shortcuts and other features, aggressive copyright stiking policies, aggressive promotion of shorts, terrible recommendations).
I am considering cancelling. However, a more optimistic view would be that their ad block policy could result in lower subscription fees with more ad and subscription revenue.
Many studies claim the response people have to the manipulation of light intensity, color, and duration, does effect several aspects of the person. Sleep hygiene does seem to play a large role, but the sun is likely the largest contributor to the human body's roughly 24 hour circadian rhythm.
What do you think about cooperative hunting between humans and dogs? Not the same as modern domestication, but some have theorized dogs may have domesticated themselves by eating scraps and/or leaving scraps progressing into sharing, hunting and training with humans. These relationships could have slowly progressed to human ownership of dogs. If we gloss over the hunting ethics, where would you draw the line for when this ethical cooperation between unequal partners turns unethical? Or do you reject the premise?
I would try to avoid the flu more if I had an idea of how much brain damage it could cause. I understand the comparison to the flu is a touchy subject, but the question can still be asked from a standpoint of curiosity. Is this disease showing completely new symptoms for a viral infection, or have we been over analyzing any little details that are not so uncommon? Does it matter? I certainly would like to know the answer.
