Are there any good voice-changing softwares out there that don't make your voice robotic?

Yes – Audacity is free recording and editing software ideal for voice-overs and singers.

You can enhance your voice using the Effects option, which is located in the toolbar. For example if you want to boost the presence and fullness of your voice go to Effects -> Compressor. Use the default setting to begin with and see if it is enough for your voice.

You can also adjust equalisation (EQ) which means adding more/less bass, mid-tone and treble.

A powerful, free tool.

Is a universe from nothing possible?

How could it be otherwise?

For a universe to be created from something would be impossible – the something would, by definition, be part of the universe. There are only two possibilities:

  1. Universe always existed (eternal inflation)
  2. Universe created ex nihilo. (Yes that means creation of everything, including spacetime, from absolutely nothing.)

Both are consistent with what we know of physical law[*] and imply a zero-energy (observable) universe.

[*] okay, the universe is not consistent with baryon or lepton number conservation, but no one expects that to be a fundamental law. Soon to be superseded by Baryon − Lepton conservation.

What would happen if you stuck in a top of the line graphics card like a n Nvidia GTX 1080 in an old motherboard from 2006?

“What would happen if you stuck in a top of the line graphics card like a n Nvidia [sic] GTX 1080 in an old motherboard from 2006?”

The best version of PCI Express that a 2006 mobo would be able to support is version 1.1. PCIe 2.0 wasn’t released as a spec until January 2007.

One of the nice things about the PCIe specification is backwards-compatibility through all versions (in theory). That means that you can put a card designed for a PCIe 3.0 bus into a PCIe 1.0a slot and have it work. You can also put a PCIe 2.0 card in a PCIe 3.0 slot and have it work.

Specifically for video cards, the caveat for backwards compatibility is that the slot must be a x16 (i.e., 16 data lanes wide) slot. It *may* work in an x8 slot but I doubt it, plus x8 slots are fairly rare.

Also, you’d need to make sure that the PSU in the system can A) provide the necessary output on the 12V rail(s), and B) have the proper PCIe dedicated power connectors for the card.

You will not get the full performance out of the higher-spec PCIe video card on the lower-spec bus; there just isn’t enough bandwidth between the northbridge chipset and the GPU with mismatched PCIe specs to allow for it.

So, to directly answer your question: Nothing much. It’ll work. You’ll be able to play games that your 2006-spec’ed PC would be able to handle in terms of memory and CPU power. It’ll just be a waste of GPU processing power (and probably cause cooling issues inside the case).

Edit: Cleaned up a couple of grammatical errors.

How to pronounce Quora and what does the word itself mean

How do you pronounce "Quora?”

'Quorum' (of whom in Latin) itself is genitive plural of 'Qui' which means "WHO". As usual, the intended definition of 'Quorum" & "Quora" has morphed into a diluted one but understandably so. "Quora", not surprising, has come to mean a 'select group'.

In Information Technology

A cluster quorum disk is the storage medium on which the configuration database is stored for a cluster computing network. The cluster configuration database, also called the quorum, tells the cluster which physical server(s) should be active at any given time.

What is the writing process like when co-writing a book?

If writing a book fills you with all kinds of dread, consider co-writing a book. We’ve done it twice now: once on A Mind at Play and earlier on Rome’s Last Citizen.

We’ve found it to be an enjoyable experience both times. You get a few built-in advantages when you’re co-writing a book, and they help to address a lot of the hurdles that keep people from writing books on their own:

1) You only have to write “half” a book! Okay, so that’s not entirely true, but with two people, you do double your capacity for research, writing, fact-checking, and all the rest. It also helps to have two people pushing hard to get that all-important first draft done quickly.

In our case, we would split up the chapters, write them, and then share the result with the other person. It made the whole thing go by much more quickly than if we had been working on it alone.

2) You’re accountable to someone who isn’t you. It’s easy if you’re mid-book to find every excuse in the world to not write. Writers will joke that they rarely have cleaner apartments than they do when they are mid-project. And that’s because writing is hard work, and for many of us, we manage to find other “productive” ways to spend the time we should spend writing.

Hence why it’s great to have a co-author. You’re not writing for you; you’re writing for them. They need the chapter because they have to edit it. You signed the contract together, and you can’t skimp out on your half of the work. It’s a commitment device that’s impossible to shake.

3) You’re not alone with your thoughts. In the writing of both of our books, we’d often look up from our laptops and talk out loud about a scene, a chapter, an idea. It was great to have someone around who you could bother with things like that. (It’s also an enormous relief for family members who get tired of hearing the same fact over and over again.)

That intellectual companionship is more important than you might think. Writing can be lonely. Co-authoring a book is a wonderful cure for that, and it gives you someone else to test your ideas before and after they hit the page.

4) You leverage each other’s strengths. We each enjoy, and are good at, different aspects of the writing and book process. But in doing a book together, we get to benefit from what we each bring to the table. If one person is a better interviewer, let them handle interviews. If one person sets scenes better, they tackle that.

It can seem like a simple thing, but it’s especially helpful in those moments when you don’t know if you’re equipped to tackle a particular paragraph or section. You can turn to the other person and say, “Hey, do you mind just dropping in here for a few minutes and handling this? I think you’ll be better at it than me.” That’s invaluable when you’re trying to finish a book.

5) It’s much more fun. It helps, of course, to have a co-writer whose company you enjoy. If you can find that, then you’ll have a lot better time writing the book as a whole. You laugh at the same inside jokes; you celebrate the successes together. All the nerdy, quirky things that make up a book process just become more bearable and interesting when you’re doing them with someone else.

How to solve this Cauchy problem [math]z' = (z + 4x) ^2[/math], [math]z(0) = 2[/math]

First step is to expand the right side:

[math]\frac{dz}{dx} = z^2+8xz+16x^2[/math]

This is a Riccati equation: see Riccati equation – Wikipedia

if we let [math] u = z+4x, \frac{du}{dx} = \frac{dz}{dx} + 4[/math], we can write this equation as [math]\frac{du}{dx} – 4 = u^2[/math]

This equation is just separable, so we just have

[math]\frac{du}{u^2+4} = dx; \frac{1}{2}arctan(\frac{u}{2}) = x+C; \frac{1}{2}arctan\frac{z+4x}{2} = x+C[/math]

Now we plug in the condition:

[math]1/2*arctan(2/2) = 0+C; π/8 = C[/math]

So, your solution should be

[math]\frac{1}{2}arctan\frac{z+4x}{2} = x+\frac{π}{8}[/math]

in implicit form.

How to talk like a native English speaker

First of all, you need practicing. Not just for one week, one month or one year. You have to internalise learning process in your life. Cultural adaptation is an important aspect of language acquisition.

I can divide your question into two part.

  1. Gaining fluency
  2. Accent like a native speaker

For gaining fluency, there is one thing to do. Practice!

Gaining native accent is a little bit difficult than the fluency. You should imitate natives. You should be careful about the stress of the words and sentences.

In order to gain native accent I can suggest several activities:

1) Prosody :

Listen to native speakers carefully. Learn rise and falls of sentences. It will improve your accent

2) Vowels

Learn where in your mouth English vowels are pronounced. It will make a huge difference in how the native listener understands you.

3) Consonants

Pay special attention to consonants.

4) TV Shows

Pay attention to TV shows. Listen to how others pronounce words on TV.

5) Phonetic Alphabet

Learn phonetic alphabet and get an English dictionary with IPA symbols

6) Converse with native speakers

Regular practice is the most important thing for improving the acquisition of perfect accent

7) Choose the accent

Pick the accent you want yours to sound like, and immerse yourself in a world of resources that are spoken in that accent

8) Read out to yourself

Put your phonetic alphabet and English dictionary near to you and read a book loudly.

9) Sing some cool pop tunes

10) Listen formal British accent can be heard on BBC news.

11) Imitate a native speaker

There isn’t one solution for all of those suggestions. Yet, English Ninjas would cover most of them. Practising with a native tutor would be a perfect solution for both gaining fluency and native accent.
