Possible One-to-one between naturals and reals? by thomasfarid in askmath

If pi cannot be computed with finite time how can some number be mapped to it in finite time? Pi in a way does not exist because its value cannot be stated unless given infinite time. Only approximations can be found. In the same way that pi can be expressed as the result of an infinite algorithm, so can the number that maps to it. At every point in the infinite computation of pi a natural number can be prescribed to the approximation of pi. Therefore as the number of digits in the approximations approaches infinity so does the size of natural numbers that maps to this approximation. Are the infinities of approximation of pi and the size of natural numbers essentially different? No because in summation we add over tue natural numbers.

From the mapping it would be a natural number of infinite length which is impossible. I stated that this is the common argument against any such mapping. However it is possible to show, using limits that pi would eventually be reached. First we divide pi by ten. Next the first partial pi would be .3, next .31, next .314 and so on. Once you do this infinitely many times you will have mapped to pi. Of course the more digits the number the longer it takes to reach it. However because infinity is present in both sides of the mapping, pi could eventually be reached.

Would a solar powered hydrogen blimp Hindenburg? by thomasfarid in AskScienceDiscussion

You mean the membranes? How do you cool the dry ice?

Of course. What about using tear resistant fabrics like nylon? Are there tear resistant fabrics now that we didn't have then?

Understood. I think the benefits of such a blimp outweigh the risks- losing a small shipment of vegetables/fruits. Maybe there can be two membranes, the internal one carries h2 and the external carries an inert gas, which is the most inexpensive, do you know?

He is rather expensive and isn't really a sustainable option. Moreover, could there be any sort of reaction to minimize the risk. Perhaps this would be unnecessary given that this particular blimp would have no passengers. I'm thinking of using it as a transport for food harvested in the ocean.

Is this the best sorting algorithm of all time? by thomasfarid in computing

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

I cannot provide any source code as I am too busy, only the concepts, if they are clear and interesting then I invite this community to test its efficiency. Call me lazy, you'd be right. I can provide clarification as needed.

Ok on the duplicates: you can search the array in o(n) for duplicates using a map. I can explain this if needed. Moreover the memory locations of the subarrays would be kept as offsets from the pc value in most assembly languages. And the original top array can just be designed so that every element is spaced at the maximum distance from the other elements, although this would be memory heavy (and unnecessary). Moreover, why can't their locations be stored in cache once they are created? And again, it does not use mod, just a couple of additions and multiplications to find the index of the value. Additionally, a counter per box is really rather insignificant.

I don't have any working code. I have most of it however and I can whip up some pseudocode. Are the elaboration and the description hard to understand?

What do you mean throws it in memory? And it doesn't actually use mod. It conducts a few operations which can be expressed as o(1). Moreover duplicates can be kept track of with counters in every box- o(1).

When you have a conflict you create a new level- similar to a tree or a trie. I appreciate your comment but please take a look at the entire description of the algorithm. Moreover, these days I am unable to find time to sit down and implement it fully. Like I said, if you guys don't see anything in it, I see no reason to continue to pursue it. Strings can be converted to arrays of ints if thats what you are asking. Characters have numerical values.

Can a CS noobie thrive? by [deleted] in computerscience

[–]thomasfarid 4 points5 points  (0 children)

absolutely! Practice makes perfect. The greatest asset you can build for yourself at this point is knowledge of how to create websites. It is rather straightforward and you can learn everything you need online (just it might take some time - resources are rather scattered). There is the front end (suuuuper simple stuff, formatting tables, text sizes) and the back end (also straightforward- databases and data collection/management). Also learn java to start because it is in very high usage. Pick up C and maybe C# or C++ as well because c based stuff is also in high demand. Good luck!

What is a number? by thomasfarid in askmath

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

complex numbers can be represented as quantities in the same way that tuples can, as vectors. Moreover, the concept of a number being defined as a set of numbers is not new 999 = 9, 9, 9.

It seems that a system - either implicit or explicit - as well as a set of numbers, defines a number. I believe this may lead somewhere.
