I'm thinking... Star Crunch?What flavour ice cream?
Damn few -- almost entirely just those few that are actually interested in learning the fundamentals. Most of today's students have been indoctrinated in the mentality that learning how to do anything themselves that a calculator or Google could cough up answers for them is a total waste of their time and effort. They firmly believe that doing so is nothing but useless memorization.I wonder if any new engineers know how to use a slide rule??? That's all we had, oh, and a pencil (not a Biro) and paper!
I'm uncertain -- But then congealed fat/sugar solutions (e.g. ice cream, eggnog batter, etc...) are all equal (equally revolting) to my delicate sensibilitiesIs that made by Tom and Jerry?

Vanilla.What flavour ice cream?
Ah, yes, but ice cream can have more calories than particles.Hopefully this isn't too much of a spoiler, but it is estimated that there are about 10^80 to 10^85 fundamental particles in the known universe.
It sure seems that way -- especially the next morning!Ah, yes, but ice cream can have more calories than particles.
Like I said -- 10^100 is a HUGE value!Hopefully this isn't too much of a spoiler, but it is estimated that there are about 10^80 to 10^85 fundamental particles in the known universe.
I can think of quite a few people who, were they to taste such a sweet demise, it would be a decidedly positive number.If you tried to eat that much you would be dead. So it is a negative number.
Another vocabulary lesson.Awaiting the 28'th with bated breath
I expected a PSA topic to align with one of your specialties. Let's see if anyone calls you for the cross-over into HP's work space.Sorry for the hijack, but this has been a public service announcement.
HP doesn't explain herself unless you call her out...so I did.I expected a PSA topic to align with one of your specialties. Let's see if anyone calls you for the cross-over into HP's work space.
I've not explored the etymology, howbeit such was/is my assumption also -- Seems "Shakespearean leanings" will outNow I see it in print and assume the origin is, "abated".
Off hand, it seems (as regards modern usage) that "abate" is well nigh synonymous with "ameliorate" -- I can but guess that 'abate' was formally applicable to moderation in general (as opposed to its current restricted sense of 'moderation of adversity') -- But hey! These are merely 'lexical musings' to be 'taken' at the reader's perilI expect to see a treatise on the difference between, "bated" and "abated" any minute now.
To be filed alongside: "for all intensive purposes", "At your beacon call", "For crime out loud", "You've got another thing coming" and, most egregiously, confusion of "sufferance" and "suffrage""Someone should of"
@Hypatia's Protege wait no longer, because I cannot.
First, recreating my estimate attempt and estimate and then actual numbers.
So, my Mr. Estimator hat on...
I start with something I remember from high school days - Speed of light is 3 x 10^8 m/s (that's 286,282 miles/second for you non SI unit types)
- need to convert from meters/second to decimeters of light travel in a year.
3 x 10^8 m/sec = speed of light
x 10 dm/m (a cubic decimeter is a liter which is easily converted to a kilogram later).
================
3 x 10^9 dm/sec
x 3600 sec/hr
=============
1 x 10^13 dm/hr
x 24 hr/day
=========
3 x 10^14 dm/day ((((( Here I was already able to make my guess on 10^50 because we were not going to get close to 10^75 and running out of my 30 seconds of thinking time, then I continued to see how close I could get))))
x 365 days/year (round off 3 x 365.25 = 10^3)
==============
1 x 10^17 dm/year (distance in decimeters that light travels in a year)
cube to get volume, that is, multiply exponent by three, (17 x 3 = 51)
1 x 10^51 liters
density of ice cream = 1.1 kg/liter
1 x 10^51 (liter to kg conversion is not significant)
2000 Calories / kg - (I remembered hearing ice cream was 2 calories per gram)
================
2 x 10^54
================
I repeated this effort while driving and explaining to my passenger and ended up with 10^48. I was off by a factor of "a lot" (two million) but the options differ by "a lot a lot". These are very big numbers and very big differences between 10^50 and 10^75. Very big does not mean 25% or 33% difference, it means a whole lot of difference!
==================
==================
==================
Now, with exact numbers...
==================
Starting from miles/second because I memorized that to more significant digits than all other units an I am too lazy to look any thing up for this...
186282 miles/second
x 5280 feet/mile
x 12 inches/foot
x 2.54 cm/inch
x 0.1 dm/cm
===========
2.99792 x10^9 dm/second
x 3600 sec/hr
x 24 hr/day
x 365.25 days/year
===========
9.46071 x 10^16 dm/year
The sides of our cube are 9.46071 x 10^16 dm
Cube this number to get liters.
8.46781 x 10^50 liters in one cubic light year
convert to kg, multiply by 1.1 kg/liter
9.31458 x 10^50 kg ice cream
at 2070 Calories (kcal) / kg (per Wikipedia)
=====================
1.92812 x 10^54 Calories / cubic light year
=====================
Error from estimating = 4% (I was surprised and very lucky)
NOTE1: Notification of any errors is appreciated. Nit-pickiness about significant digits is not.
NOTE2: I realize the correct answer was not given as an option.
NOTE3: If I had to select an answer in the closing seconds of a multiple choice test, I would have picked "way more than 10^100" but 30 seconds of effort and I felt reasonably safe that I had the right answer (10^50).
