Superpower's super problem: Danger not from the enemy, but from defecation...

 The world's most modern and expensive (worth about $13 billion) aircraft carrier, the USS Gerald R. Ford (CVN-78) , is currently grappling with a very strange but serious problem.

USS Gerald R. Ford (CVN-78) is the US Navy's newest, largest, and most advanced nuclear-powered aircraft carrier. She is the first of the Ford class, built to replace the aging Nimitz class ships.

Even though it is ready to face enemy missiles and drones, its "sewage system" has been a thorn in the side of the Navy.

The ship is equipped with a vacuum toilet system similar to those found on commercial airliners. According to experts and a 2020 report by the GAO (Government Accountability Office) , this system is too small and fragile for such a large ship carrying over 4,600 troops.

Expensive cleanings (Acid Flushes): Calcium deposits and debris frequently build up in this system. To clean it, the Navy must perform an "acid flush" of the entire system. Surprisingly, a single acid flush costs approximately $400,000 (approximately ₹3.3 crore) . Several such flushes have been performed to date.

It is ironic that a ship equipped with futuristic technology like laser weapons and electromagnetic catapults (EMALS) is troubled by a basic human need, i.e., 'waste management'.

A major embarrassment to the US Navy.

Since Donald Trump is known for his business acumen and "cost-cutting," this issue must be on his radar. 😁🤣

As president, focusing on military facilities should be a priority. The problem of onboard restrooms directly impacts the lives of soldiers.

What's a cool math fact you can easily tell a layman and look super cool?

 

• You can get any real number from $0$ to $\infty$ by using only four 4 digits$(4,4,4,4)$. For example
• $(4+4)-(4+4)=0$
• $(4÷4)÷(4÷4)=1$
• $(4÷4)+(4÷4)=2$
• $(4\times 4-4)÷4=3$, and son on…

• Look at this expression. ${(1+9^{-4^{6\times 7}})}^{3^{2^{85}}}$

• The above expression contains every digit from $1$to $9$
• Now take out a calculator and solve the expression. You will get approximately $\mathrm{2.718281828459.}$Which is value of $e$(Euler's number)

• Magic of Digit $9:$
• Divide $1$ by $9^2$. You will get every single digit from $1$ to $9$ after decimal point except $8$.
• $\frac{1}{9^2}=0.012345679012345679\cdots$
• The missing number $8$ in the sequence is first digit of $81$ which is $9^2$
• Divide $1$ by ${99}^2$. You will get every two digit number from $00$to $99$ except $98$.
• $\frac{1}{{99}^2}=0.00,01,02,03,04,05,06,07,\cdots ,96,97,99,00,01,02,\cdots$
• The missing number $98$ is first two digit of $9801$ which is ${99}^2$
• Divide $1$ by ${999}^2$. You will get every two digit number from $00$to $999$ except $988$.
• $\frac{1}{{999}^2}=0.000,001,002,003,\cdots ,996,997,999,000,001\cdots$
• The missing number $988$ is first three digit of $988001$ which is ${999}^2$
• Isn’t it cool?

• Infinity ($\infty$)
• When you think of infinity, the only thing that might hit on you brain is that the infinity is largest number. Well that is not true.
• When you move towards right direction on number line, you get closer to the $\infty$. While, when you move towards left, you again get to $\infty$. Most people think that the infinity is infinity, whether it on left side of number line or on right side. Well it is not true. The right infinity ($+$$\infty$) is largest possible value while left infinity ($-\infty$) is smaller than every number except $0.$

• largest Prime Number :
• The largest prime number discovered so far is $2^{74207281}-1.$
• Professor Curtis Cooper discovered this number. He used 800 university computers to work on this project .
• This number contains over 22 million digits. More precisely $22,338,618$ digits.
• The book on which that number is printed contains three volumes and is available to buy. Good opportunity for book readers.
• This number is 5 million digits longer than previously discovered largest prime number which was also discovered by Professor Curtis Cooper. He held this record four times. yeah! he is Captain Prime.
• The computers took months to check if this number is prime or not. Imagine doing this for countless numbers.
• Isn’t it super cool?

• Why $0!=1$ & why Factorial of negative number is not defined:
• Let’s take $5!$ for instance. We know that $5!=\frac{6!}{6}=120.$ Let’s write a pattern by following same logic.
• $4!=\frac{5!}{5}=24$
• $3!=\frac{4!}{4}=5$
• $2!=\frac{3!}{3}=2$
• $1!=\frac{2!}{2}=1$
• Now comes $0$
• $0!=\frac{1!}{1}=1$
• Edit : This is not a perfect proof.
• So mystery solved…
• Now get towards negative numbers by following same pattern …
• $-1!=\frac{0!}{0}=\frac{1}{0}=\infty$ (OMG)
• Read next fact to know why $\frac{1}{0}=\infty$

• Edit : More facts are coming. Let me think for a while…

Edit : Here comes another one

• Why any number divided by $0$ is $\infty$?
• Let’s take an example of $\frac{16}{4}$ for instance.
• To divide $16$ by $4$, we subtract $4$ from $16$ until we get zero $0.$
• $16-4=12$ , $12-4=8$ , $8-4=4$, $4-4=0$ , We got zero…
• So, the number of times we subtracted 4 from 16 is the answer of $\frac{16}{4}$
• $\therefore \frac{16}{4}=4$ ($\because$ subtraction was 4 times)
• Now do the same for $\frac{25}{5}$ for another example
• Subtract $5$ from $25$ until we get zero
• $25-5=20$ , $20-5=15$ , $15-5=10$ , $10-5=5$ , $5-5=0$
• We did the subtraction five times. So the answer is $\frac{25}{5}=5$
• Now let’s move on with $0$
• Let’s take $20$ and divide it with $0$ by following above method
• Subtract $0$ from $20$ until we get $0$
• $20-0=20$ , $20-0=20,20-0=20,20-0=20,20-0=20,20-0=20,20-0=20,20-0=20,$ whoop
• So, We will get zero $0$ by subtracting $0$ from 20 for infinity times
• Therefor $\frac{20}{0}=\infty$

Now you can look super cool by telling these facts…
