Proper title tags are required for all posts or it will be removed! The tags accepted are at the end of the sidebar down there.
State clearly what is being or what you want calculated in the title. [Request] posts must have a calculable answer; otherwise, they will be removed.
Give credit where credit is due—include the user who made the calculations in any post you submit: ex. "[RDTM] /u/FragTheWhale calculates...".
For easy and quick math results (ex. How many feet are in a mile?) use Wolfram|Alpha™. Posts containing "simple math" will be removed, as well as requests whose answers are easily searchable online, and any other post at the moderators' discretion. For more abstract math, try /r/math or /r/learnmath.
Posts which seem to be asking for help on homework will be removed. Try /r/homeworkhelp or /r/cheatatmathhomework instead.

Hello! Sorry if this post isn't formatted correctly; it's my first time posting here!
I wanted to ask: Any River Monsters fans here? I wanted to see if we could calculate how large the stingray in this video (https://youtu.be/bI0NSCF8H9E) could have been to bend the rod at such a hard curve - AKA, how much weight could have been behind it. From what I could find, Jeremy used braided nylon filament line and a carbon fiberglass rod designed for ocean fishing, and he apparently called the gear "marlin gear", if that helps anything, and he's made comments that he's around 175 pounds himself.
To compare, the stingray that Jeremy did succeed in catching weighed around 400 pounds, and I think he estimated that the lost stingray was around 700 pounds.

LTT just made a video wrapping a Porsche (Taycan 4S) to make it glow. If you instead covered this car in old paint from the 1950s made of tritium or radium so that it glows all the time how much of either material would be needed and what would it cost?
Let's assume they're 90kg
considering the fact that each titan is about 15 meters tall and low estimates would be 2-3 and high estimates would be 4-6 times stronger than a human of equivalent size (source:Eren carrying that rock), how strong would the bite force of one of these dudes be??
For starter i don't know if this is calculable, if it's not i apology.
In my office we are 8 people and there is 4 people with following birthday 4-5-6-7 december (not the same year). Can the odds be calculated ?
(i know about the birthday problem, with a group of 23 people there is a 50% chance of 2 people having the same birthday, maybe there is something like that)
This may be a long shot but I figured this community was the place to go. On October 18 the website for the band bon iver updated their landing page with two identically colored squares on either side of the page - https://boniver.org. As you can now see the square on the left is gradually changing to a lighter shade. Working theory is that it will become a hue on salmon that is heavily featured in promotion of their EP (see attached photo). Based on the start date of 10/18 and the current hue of the left square can anyone calculate a potential date that it may fully reach the salmon color? Like I said it’s a long shot. Thanks so much for any help!
Came across this website that measures the % of how "perfect" the circle is... Wondering what metric can you use for that? And in general, how can you measure how "circular" any curve is?
Mor info- there is only one dot that represents the center of the circle. The radius doesn't seem to matter in the calculation from my multiple attempts. However, it does say too close when you try to draw a circle with a very small radius.
Title. Also, when adding oxygen, assume that oxygen is being added to our pre-existing atmosphere, not replacing current chemicals (Eg. Pressures will go up as well).
Asking for a friend.
So I have two interconnected tanks, a big and a smaller one as shown in the attached screenshot. The goal is to find the total capacity of both tanks in cubic metres.
I made the calculation in two different ways and the results were different. I cannot explain why... Any thoughts?
Calculations:
Calculate the cubic meters of each tanks and sum them together at the end (in the screenshot green arrow/rectangular). This returns 0.861m³
Sum up the width, length and heights of both tanks and then multiply their totals to find the capacity (in the screenshot red arrow/rectangular). This returns 3.169m³.
I know that the first calculation is is the correct one as I know that the capacity of both tanks is approximately 1m³.
So, the original DNA (lets call it "22" because both single strands have extra info we dont want) splits into two "21" (one original with 2 residues, 1 recreated, with 1 residue). Like so, 21 becomes 21 + 11; 11 becomes 11 + 10; 10 becomes 10 + 00 (the desired DNA, assuming im understanding correctly)
Now, I get that the original dna (22) dissapears, and that "21" becomes a constant at 2, but does the correct (00) sequence ever becomes predominant or will it always be shadowed by partially correct ones? And if so, at what cycle?
Thanks in advance!
