#978073 Ethics of using Stem Cells to Create Human Chimeras

Posted by fiveworlds on 23 March 2017 - 07:41 PM

What a great topic. We have been modifying animals for years to produce insulin for diabetics etc. I would think that so long as the animals is not in considerable pain throughout life and the mutation isn't spread to the rest of the animal population then it is fairly okay.

#978046 Speed of depressurization

Posted by fiveworlds on 23 March 2017 - 05:15 PM

Gas Dynamics?? There are a few equations most have to do with pipelines such as.

Simplified gas formula

This formula is recommended for most general-use flow applications.


Weymouth equation

The Weymouth equation is recommended for smaller-diameter pipe (generally, 12 in. and less). It is also recommended for shorter lengths of segments ( < 20 miles) within production batteries and for branch gathering lines, medium- to high-pressure (+/–100 psig to > 1,000 psig) applications, and a high Reynolds number.


Panhandle equation

This equation is recommended for larger-diameter pipe (12-in. diameter and greater). It is also recommended for long runs of pipe ( > 20 miles) such as cross-country transmission pipelines and for moderate Reynolds numbers.


Spitzglass equation

The Spitzglass equation is recommended for low-pressure vent lines < 12 in. in diameter (ΔP < 10% of P1).

The petroleum engineer will find that the general gas equation and the Weymouth equation are very useful. The Weymouth equation is ideal for designing branch laterals and trunk lines in field gas-gathering systems.

That isn't supported by html it requires using css and isn't included in bbcode. You can use [LIST=a].

#976323 What is this function ?

Posted by fiveworlds on 14 March 2017 - 06:16 PM

Not sure how to solve it though

It is an infinite loop.

public static void function(int x){
  int answer = 0;
  int p = 0;
    if(p%2 == 0}{
​       answer = answer + java.lang.Math.pow((x/2),​2p)/java.lang.Math.pow(factorial(p),2)
    } else{
       answer = answer - java.lang.Math.pow((x/2),​2p)/java.lang.Math.pow(factorial(p),2)
​​       system.out.println(answer);


public static int factorial(int n) {
   int result = 1;
   for (int i = 1; i <= n; i++) {
      result = result * i;
   return result;

#975710 [Shocking?] Neil deGrasse Tyson: "Science is true whether or not we belie...

Posted by fiveworlds on 11 March 2017 - 11:35 AM

Why belief is non-necessary (written by inventor of "non beliefism")


It took billions of years of evolution on planet earth, for a phenomenon called 'non-beliefism' to emerge, and I am its inventor.


Non-beliefism is a framework that may enhance thought, while underlining that belief is non necessary, for belief opposes science.


Here is one of "non beliefism's" premise sequences:

Separately, belief may constitute non-science.
Science in contrast, shan’t encode non-science.
…ie scientific evidence shan’t contain non-scientific-evidence.
Thereafter, it is non-scientific to believe.

Simply, it is non-scientific to believe, as the concept of belief allows non-science, whereas science allows not non-science.

Therein, one need not contact a paradigm, observed to likely express non-science (i.e. belief), whence science persists.


Criticism is welcome.



You didn't invent atheism.... Don't you have something better to be doing with your time???

But if the virus is actually a trojan or key logger, and someone steals all the money from your bank then all those backups won't help​



Not necessarily your bank can keep track of your frequently used devices and public ip address and notify you of irregular money transfers. Also you won't lose all your money if your house happens to burn down. Also paypal isn't all that secure either accounts are sold on the dark web.

The virus has to get there first. It's only possible if its occurs



It did to me so I don't see it as an unreasonable problem. If I use a bank I know that my data is at least backed up in triplicate in multiple datacentres bitcoin has nowhere near that level of security.

#961651 Let's talk about Bitcoin

Posted by fiveworlds on 14 December 2016 - 05:10 AM

The main problems with bitcoin are


1. Security

2. Black Market


From a security standpoint it is possible to get a virus on your computer and therefore lose the bitcoin wallet. Bitcoin provides a fairly untraceable online currency for criminals to exchange goods.

#961541 Profound speculations on the Speed of objects

Posted by fiveworlds on 13 December 2016 - 04:35 PM

What happens to the energy for values that exceed c?



When Cherenkov Radiation was discovered Einstein revised GR and wrote SR which allows for the existence of Tachyons. Stating that if a particle exceeds c it will always travel faster than c unless an external force causes it to slow down.

#958472 Ideal way to dry washed dishes in a commercial kitchen?

Posted by fiveworlds on 25 November 2016 - 12:27 AM

Dishes washed in boiling water will dry faster than those washed in lukewarm water. You shouldn't need to be drying dishes with a tea towel they should air dry very quickly if washed in boiling water. Usually restaurants have a conveyer belt washer and dryer system.

#958438 How to get a job?

Posted by fiveworlds on 24 November 2016 - 08:42 PM

Few PhDs actually develop their own products. What you market are your skills.​



Obviously but there is also the possibility that jobs in your field won't be around when you leave college. Your skillset could be completely irrelevant to 95% of the job market in your locality with you being in competition with other highly qualified people for the role. Most people with PhDs are already married with kids and there may not be the option to move for work without leaving the rest of the family behind.
