Thank you. I had fun and it only took a few minutes to look things up.
It invigorates my curiosity level. Wish it would do so for memory retention!

Regarding the Question on Dihydrogen Monoxide:

DHMO is correct. Some people say that water, H2O, is dyhydrogen monoxide. It really is not. Rotorhead explained this accurately below.

I received a PM asking why I said that RH's answer regarding the water was wrong. It is not wrong, but I failed to make myself clear when I stated " ***AND please note that Water would have been incorrect as described by Rotorhead sited as follows: (I posted this question to see if "water" was going to be an answer...just for fun...lol.)"

I should have said: "AND please note that WHY Water would have been incorrect is described by Rotorhead as cited below." Thank you, RH, for addressing why water was not the answer: I apologize for any confusion I may have caused because I failed to be clear enough.

Many thanks,
Swan

The dihydrogen monoxide hoax involves calling water by an unfamiliar name, "dihydrogen monoxide", followed by a listing of real effects of this chemical, often presented as an argument that this substance should be regulated, labeled as hazardous, or banned. The hoax is intended to illustrate how the lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.

"Dihydrogen monoxide", shortened to "DHMO", is a name for water that is consistent with basic rules of chemical nomenclature, but is not among the names published by IUPAC and is almost exclusively used in a satirical context. Other chemicals names that also indicate water, usable in hoax variations, are hydroxyl acid and hydrogen oxide.

G'afternoon everyone: Shall we mix a bit of Ocean with a bit of Physics? Enjoy!

1. Reaching lengths of 40 feet and more, weighing more than 20,000 lbs.,being the largest 'fish' in existence, feeding on plankton - small fish - shrimp like animals - and whose lifespan is estimated to be 100 yrs. or more, who is this magnificent and gentle creature?

2. What is the smallest shark?

3. What is the 1st. subatomic particle to be discovered?

4. If light is passed through ultra cooled rubidium @ -273.15 degrees C., what will happen?

5. What is the diameter of a proton (in a nucleus)?

Hi JJ,
#1 . Yes it is the Whale Shark!
#2 . Yes it is the dwarf lantern shark!
#3 . Yes. It is the Electron!
Well done!

Two Questions remain: Anyone interested?

4. If light is passed through ultra cooled rubidium @ -273.15 degrees C., what will happen?

MIT and Harvard create new, lightsaber-like state of matter: Photonic molecules

Now, however, the Harvard and MIT researchers, led by Lukin, have managed to make photons behave almost as if they’re normal, massive particles. To do this, the researchers pump rubidium atoms into a vacuum chamber, and then cool the vacuum down until it’s a few degrees from absolute zero. Extremely weak laser light — a stream of single photons — is then shone through the rubidium-filled vacuum. As individual photons travel through the medium, it loses energy to the rubidium atoms, slowing down. When the researchers used the laser to fire two photons, instead of one, they found that the photons became a two-photon molecule by the time it left the medium.

Interesting article...

G' afternoon Skywatchers,

Everyone knows that I admire Jupiter: Jupiter arranged the Solar System by demolishing planets to form what is known as the asteroid belt located between her and Mars; she hurled out of the Solar System huge planets, some of which are rogue and whose fate is to forever wander alone throughout the universe - planets with no Suns of their own; she captures asteroids, many of which target Earth - she protects Earth; and with her 67 Moons, she longed to be a Star with a Solar System of her own!

On the evening of March 9th, high above the Moon in the Southern sky, Jupiter will appear like a bright and beautiful Star in her own right. She will be the brightest 'star' in the night sky - even if for only one night.
Enjoy!
Swan

G'afternoon everyone,

I have an idea, which is also a challenge! Shall we put science aside for a minute and have fun with math, although these questions are NOT the easiest to answer. Don't get discouraged; just have fun!

1. What is the number that is one more than 1/10 of 1/5 of 1/2 of 4000?

2. What is the 4-digit number in which the 1st digit is 1/5 the last, and the 2nd and 3rd digits are the last digit multiplied by 3?

3. The day before the day before yesterday is 3 days after Saturday. What day is today?

4. Complete the following sequence of numbers: 1,2,4,7,11, ? , 22.

#1 0.02, 2,000

#2 1155

#3 Thursday

#4 1, 2, 4, 7, 11, 16, 22

Thanks Swan, I would love to tell you that JJ and I answered these questions but we had to call my math whiz daughter. At least we learned how to figure them out.

Almost!
Question #2 and Question #4 are correct; Questions #1 and #3 need a bit more work.
Well done!

1. What is the number that is one more than 1/10 of 1/5 of 1/2 of 4000? Yes. 41 (4000/ 2 = 2000; 2000/ 5 = 400; 400/10 = 40 +1 = 41)

2. What is the 4-digit number in which the 1st digit is 1/5 the last, and the 2nd and 3rd digits are the last digit multiplied by 3? Yes. 1155.

3. The day before the day before yesterday is 3 days after Saturday. What day is today? Yes. Friday

4. Complete the following sequence of numbers: 1,2,4,7,11, ? , 22. Yes. 16. (Each number adds 1,2,3,4,5,6 respectively to the
proceeding number).

Yes Tammy and JJ. Well done and congratulations! I chose these questions from tests given to Mensa candidates!

Thanks Swan! We love trying to figure out your questions. Even when we can't figure them out we learn new things. There is a great website called mensaforkids that we go to when we get tired of our drill and kill math. lol. Today we are learning about fabulous Fibonocci and his nifty numbers.
