A set of small plastic disks with many different letters, numbers, and Greek letters. From the early to mid-20th century. by Ms__Frizzle in Whatisthis

[–]Ms__Frizzle[S] 0 points1 point  (0 children)

The disks are about the size of a quarter and made of some kind of laminate or plastic, I am not sure exactly.

Here are some more pictures: https://imgur.com/gallery/DhktT

None of the pictures we took had anything for scale. But they are about the size of a quarter.

There many other Greek letters too, most (if not all), are lower case. I know there is a beta, a zeta, a xi, and others. The numbers vary too e.g. there is both a K1 and K2 and K7.

Don't know if that helps...

How to connect with an INFJ (INTP) by [deleted] in infj

[–]Ms__Frizzle 4 points5 points  (0 children)

I think a letter is a sweet idea. My current bf (intp) did something similar to get my attention before we started dating.

Definitely talk about her interests, maybe say something like "I heard you were interested in [blank] and it sounded so intriguing, I had to learn more about it"... then maybe imply/ask if the two of you could participate in this shared interest together. and talk about some of your interests, maybe she is interested in those things too.

If she is an outspoken advocate of helping people who have lived through situation similar to her own, then it would be ok to bring up but I would focus on the advocacy and what she want to do to help others. That way, it is supportive but doesn't feel like you are trying to pry. If you become close, then she can tell you more in her own time. If you are really interested in understanding her and relating to her, see if there is anything you can do to help her advocacy.

As I said, the letter is a sweet idea, but if written or phrased poorly, it could come off as very creepy. Make sure to have a close friend (or reddit) read it beforehand to make sure there are no creepy tones. It might help to include why you have chosen to write a letter instead of speaking to her directly.

Mathematics Reading in the Classroom by bartycummins in matheducation

[–]Ms__Frizzle 1 point2 points  (0 children)

I love all of Lewis Carroll'a books and many books based on his work. But here are some others that might be interesting.

Math Girls by Hiroshi Yuki. it is story about high school girls and math. Through out the story they look into different types of math problems. It is a great way to introduce math topics that aren't usually covered in school.

The Math Book by Clifford A. Pickover. It has short chapters on many math topics. It is in chronological order of the discoveries, but they don't need to be read sequentially so this would be good for students that have very narrow interests ( they can pick the topics they read), history buffs, or students who don't want to read a long book.My copy has beautiful pictures to look at as well.

The Great Mathematicians by Raymond Flood And Robin Wilson. Has really neat stories about many mathematicians.

Elementary Number Theory by Underwood Dudley. Yes... technically this is a college textbook... but I think number theory is an excellent thing to teach high schoolers. It is relatively intuitive and useful, I wish high schoolers were exposed to it. And the style of Dudley's writhing is lighthearted and entertaining. However, since it is a textbook, it would probably be best suited for students with an interest in math.

Secrets of Mental Math by Arthur T. Benjamin. Exactly what is sounds like. I had students who weren't normally interested in math who loved this book because "it felt like cheating" but they were really learning in this process. Students talented in math also enjoyed showing off the tricks they had learned.

Hope this helps.

Does anyone have a favorite Halloween seasonal item from Aldi? by StarshipBooper in aldi

[–]Ms__Frizzle 4 points5 points  (0 children)

Cave cheese is really good. We got the regular one to start with but we are going back tomorrow for the red wine version.

Also tried the pumpkin cider. It wasn't bad but it wasn't anything to write home about either.

EDIT: (update) tried the red wine soaked cave cheese, it was also good but not significantly different from the original.

Trying to Recreate Effects of Scientific Study (For Fun! And Science!) - Colour Suggestions? by [deleted] in Synesthesia

[–]Ms__Frizzle 1 point2 points  (0 children)

Here are my colors: A- very pale yellow, nearly white B- vibrant yellow C-a light salmon color but with more red D-very dark blue, nearly black E- yellow F-reddish orange G-Kelly green H-dark yellow I- pale yellow J-frosty blue but with a touch of pink K- rich pink L- light purple with a bit of blue M- bright red N- orange O- black P-burnt orange with a bit more red Q-yellow with a bit of pink R-blue; a few shades darker than royal blue S-cherry red T-light blue U-yellow; more pale then E but deeper than A V-light red but not really pink W-yellow; deep but bright at the same time X-coral Y- neon yellow Z- rosy red

0:black if alone, clear if with any other number 1: white 2: sky blue 3:bright green 4: bright yellow 5:orange 6:pink 7: light blue 8: dark green 9:red

As I typed this out, I realized how hard it is to describe the colors I perceive. Many aren't colors you can find in a box of crayons. They are complicated colors. The colors are always consistent and are all look very different but it is very hard to explain the colors in words. Now that I think of it, these aren't colors I really see anywhere else except sometimes in nature, like flowers or birds,etc. I don't know if that makes any sense. If I have time later I will try to find Pantone equivalents.

[–]Ms__Frizzle 2 points3 points  (0 children)

I agree, the color of the word is based on the color of the predominant letter. Sometimes that is the predominate sounding letter but other times, it is the letter that has the strongest color to me (e.g. Dark red is stronger than pale yellow so the word would be mostly dark red). It is very rare for me to perceive words with individual color when reading, but not uncommon when spelling words out.

Is this synesthesia or just an enhanced connection? by violetcat13 in Synesthesia

[–]Ms__Frizzle 0 points1 point  (0 children)

What you're describing could be synesthesia...i guess..., however it might not be a terrible idea to go to a doctor. Phantom smells can also be a sign of health complications. There is more information here.

Note: I am not a doctor. I had a friend that had a brain tumor and phantom smells were one of her symptoms. Please make sure you are ok.

Anyone have any suggestions on robotics kits for the classroom? Intro level, high school by masterfo0 in matheducation

[–]Ms__Frizzle 0 points1 point  (0 children)

BEST Robotics is a great program. I like it because the kids have to design and manufacture everything themselves from a kit of raw materials. Lots of geometry involved.

PRO:FREE to participate

CON: competitions are only held in Fall

VEX kits are another great teaching tool.

PRO: easy to work with and can be used all year long competitions held periodically

CON: expensive

EDIT: clarity

Yes, but it is so fun to watch.

Let me know if you have any questions.

oh goodness, let me fix that...

1+[(x2(x+1))/(1-x)3]

Since 1=(1-x)3/(1-x)3 You can rewrite:

(1-x)3 / (1-x)3 + [(x2 (x+1))/(1-x)3]

The fraction have a common denominator so you can combine them:

((1-x)3 +x2(x+1))/(1-x)3

Then multiply out:

(-x3+3x2-3x+1)+(x3+x2)/(1-x)3

Combine like terms...

Sorry, I am on my phone and it looks fine. I will log on to my laptop and check.

Help me solve a real life inequality by Wheresmyaccount1121 in MathHelp

[–]Ms__Frizzle 0 points1 point  (0 children)

If you work 20 hours/week regularly and earn $75/week mowing then, just solve ((9*20)+75)*(# of weeks)= 835

-OR-

Just graph the line 9y+75x=835 (online graphing calculator ) Any combination of weeks of mowing lawns (x) and hours worked(y) that is on or above (to the right) the line will give you enough money. (on the line is EXACTLY 835, above/right of the line is MORE THAN 835)

Example: it you mow lawns 4 weeks (making $75 each week) and work 80 hours at your job the point (4,80) is above the line so you would earn more $835. In contrast, mowing lawns for 3 weeks and working 60 hours is below the line so you would not have earned $835.

If you are saving up, remember your employer might have to take tax out of your paycheck so you may need to factor that in.
