Title: The Random Facts Thread
Post by: sweetiepi on December 14, 2017, 01:32:27 pm
A place to share and learn new facts, no matter how weird, wacky or random the fact is! ;D

To start: There is a debate among scientists about whether or not fat is the sixth taste (after sweet, sour, bittter, umami, and salty).

So I was talking to Rui last night (as you do) about that little rule from that learning to drive book. I told him that I probably wouldn't be tested on it, but I kept it at the back of my mind...
This morning I had the test and it came up. Didn't expect it, but did have a bit of a chuckle about it afterwards. :P

Worse, you also use similar titles when being polite with family friends - and sometimes when you're trying to be thankful to someone who has helped you. Fortunately that is lumped into singular words, but they are still divided according to obvious age gaps of you relative to them.
For example, I may be called the word for "older sister" if a little boy was forced to say thanks from his mother, after I give back a toy he dropped, even though they're absolute strangers to me.

Tbh I reckon courtesy ones are easier. You use less things than in that flow chart.

I only use six. For women/girls, I would just use 奶奶,阿姨,姐姐. For men/boys, 爷爷,叔叔,哥哥.
And when in doubt with the age factor, pick the younger of the two valid alternatives. Like there's someone I know that I really could call 奶奶 but I just pick 阿姨 anyway

I use most of those words, but it gets iffy and tricky to track.

For me, I have words like first cousin, 2nd cousin, 3rd cousin etc

and sometimes if people pass away,  cousins are sort  of "replaced" by the next closest family member etc (or grandson)...

Dermochelys coriacea (aka the leatherback sea turtle) is the only testudine (turtle or tortoise (or terrapin if you're American)) that doesn't have scutes (those shapes on the shell). Instead, D. Coriacea has spiny ridges that run down its carapace (shell). This is suspected to be related to its increased dive depth, swim speed etc. in comparison to other sea turtles.

Also their brains are very ATP efficient which is suspected to aid their dive duration.

Question No. 1: Are you a turtle, or a tortoise?? ;P
Title: Re: The Random Facts Thread
Post by: Bri MT on December 24, 2017, 05:38:58 pm
Question No. 1: Are you a turtle, or a tortoise?? ;P

I've always identified more with turtles. For a long time when I was younger Chelonia Mydas (green sea turtle) was my favourite but then I started leaning more towards D. Coriacea. Honourable mention also to Chelodina Longicollis (eastern long neck turtle) for being the long time favourite inland turtle. One sign of my blatant favouritism is that I don't know the scientific names of any tortoises (shocking, I know).
(You may have been referring to CB but you get this text block anyway :P)

Here's your bonus facts:
-an ancient predecessor of modern tortoises was very, very similar in many respects EXCEPT that it had teeth rather than crushing plates in its mouth. (Modern testudines may have an egg tooth but that's it)

-in an controlled experiment eggs of the Murray Darling river turtle were monitored and it was found that the embryos were changing the rate of their own development in order to synchronise with each other. So two cool things from that:1. They can control their own rate of development  2. They were somehow (the researcher speculated it might have been odour based) communicating with eachother before even hatching

In 1984, Giant Pandas were declared an endangered species. With an increase in their population numbers and conservation strategies put in place to protect them, their status has now been changed to vulnerable. This is fantastic news! The director of the World Wildlife Fund says, “The recovery of the panda shows that when science, political will and engagement of local communities come together, we can save wildlife and also improve biodiversity.”

Other animals that were once considered endangered but no longer are include sea cows, humpback whales, the grizzly bear and the red kangaroo.

A peacock mantis shrimp can sucker punch its prey with 160 pounds (72.5kgs) of force, with the equivalent speed and energy of a .22 caliber bullet. This is so fast, it creates a superheated bubble of water that - when it bursts - can literally break apart its prey's shell and organs. The mantis shrimp doesn't even need to touch an unfortunate crab to kill it. Brutal.

According to this: https://www.nytimes.com/2006/03/14/health/14real.html (old) article:

Quote
heart attacks follow a pattern during the week. They occur at their lowest rates on weekends, jump significantly on Mondays, then drop again on Tuesdays

Quote
It found that the risk of a heart attack was about 20 percent greater on Mondays for adult men, and 15 percent greater for adult women.

Quote
problems might be linked to heavier drinking over the weekend.

Other studies have also found the Monday effect among retirees — who presumably do not have to worry about overbearing bosses and heavy workloads.

According to this: https://www.nytimes.com/2006/03/14/health/14real.html (old) article:

This is more of a trick than a random fact but now I will be able to guess your age:

1. Choose a number between 1 to 9. Any.

2. Double that number from step 1 and add it to 5.

3. Multiply your new total by 50.

3. Add this number (from step 3) to 1769 (if you celebrated your birthday this year) else 1768.

4. Subtract your birth year (e.g. 2004) from your value that you got in step 3.

5. The first number of the final three digit value is the number you chose. The last two digits are your age.

This is more of a trick than a random fact but now I will be able to guess your age:

1. Choose a number between 1 to 9. Any.

2. Double that number from step 1 and add it to 5.

3. Multiply your new total by 50.

3. Add this number (from step 3) to 1769 (if you celebrated your birthday this year) else 1768.

4. Subtract your birth year (e.g. 2004) from your value that you got in step 3.

5. The first number of the final three digit value is the number you chose. The last two digits are your age.

Is it pretty cool??
1. Start with the number \(n\), where \(n\) is an integer between 1 and 9 (inclusive).

2. New number: \(2n+5\)

3. New number: \(100n + 250\)

4. I'll use 1769 since I have celebrated my birthday. New number: \(100n + 2019\). (Suspicious.)

5. My birth year is 1998. New number: \(100n + 21\).

6. Well the digits of the number are now \(n\), \(2\) and \(1\). So that worked out nicely.

So explanation: That number between 1 and 9 was secretly left untouched since step 3. It just bubbled its way from the units digit to the 100's digit because we literally multiplied it by 100 along the way. Every other operation from there only changed the trailing number.

The trailing number made its way up to a 4-digit number once we added 1769, which was an intentionally rigged choice. This automatically made 2019 appear.

And of course, 2019 (this year) - year of birth = age.

Rule of thumb: Math is more fun when you hide the algebra going on behind the scenes

Great job! I was thinking of showing my "secret" in case someone was to ask the maths behind it, but surely I never realised that it would be revealed this quickly :)

I prefer to think of it as magic.

\[ 2020 = 17^2+19^2+23^2+29^2. \]
Spoiler
It's cool because like, consecutive primes
