Numberphile2 FAQ

Okay, here are some answers to frequently asked questions about my YouTube channel Numberphile2.

1. What is Numberphile2?

It is the second or supplementary channel to Numberphile.

2. What is it for?

It is designed to host Numberphile material that I do not want to put on "main channel" for various reasons.

3. What sort of material is that?

It could be anything. Mainly it is "extra material" cut from Numberphile videos. It could also just be stuff that I thought did not quite belong on the main channel or behind-the-scenes stuff. Maybe it is too niche, too long, too short, etc.

4. But I love seeing all that stuff, why not just put that on Numberphile?

Because Numberphile has a large following (about one million subscribers) and casual viewers do not want their feeds clogged up with "extra material" or 2-3 videos every time I put something new out. They just want the headline act.

Numberphile2 can be a channel for the real die-hards who want everything. Like a little club for the true believers! :)

5. Why not just put that "extra stuff" on Numberphile (main) and make it unlisted?

I used to do that, but the material then becomes impossible to find in searches. And some people do want to be able to have this turn up in a subscription feed in some form so they don't miss it.

6. Then why is some material on Numberphile2 still marked as unlisted?

There are a few reasons that Numberphile2 videos START as unlisted and become listed later.... The main one is this: When I release a new video on Numberphile, I probably release the "extra material" at the same time and link to it from the main video. If I made them both listed, they would turn up in subscription feeds around the same time, increasing the chances that people might watch them in the wrong order. To get around this, I make the second video unlisted so it does not show in sub feeds... I then list it a few day later.

7. Why is the logo/avatar for Numberphile2 the number 2 and not Tau?

The current avatar for Numberphile is Pi on a brown paper background - a famous "number" everyone recognises and it just looks cool. Now because Tau is 2Pi, many people think that should be the logo for Numberphile2. I agree that people who "get the joke" would appreciate that. But I think it would be confusing for people who do not. For a start, Pi has two "legs" and Tau has one. Some people might think Pi should be the second channel logo? The number two is just really clear and obvious... It says: "This the second channel". Sometimes it is best to not be too clever.

Should I subscribe to Numberphile2?

In some ways, my advice to casual viewers is "no". I will usually link to Numberphile2 material from main videos, either via links or annotations.
I will also let people know about anything great on Numberphile2 via Facebook and Twitter.
However if you are really into all the extra stuff and not want to miss anything, than of course please do subscribe. I appreciate all the support!

Special Roll

From a viewer named Patti...

My class has been studying probability and yesterday we calculated the probability of rolling a Yahtzee on the first roll.  
So, today, we watched your video.  
The students were intrigued and waited for that Yahtzee with close attention.  After the video, I told them, like you said, in the game Yahtzee, you get three tries.  
So I rolled five dice...and got a Yahtzee!  
The class and I were stunned.  Utter silence and disbelieve.  
The look of "did that really happen"  on 30 7th grade faces.  
Thank you for showing the students your perseverence of waiting through 600 some trials.  
And thank you for making my roll look so special!!

Net Neutrality

It's a big deal in the US (and the world) at the moment!

Two recent videos from CGP Grey and Vi Hart are well worth watching (and maybe acting upon?)





This video by Emily from BlinkPopShift from a while ago was also good.



UPDATE...

Oh, I missed this excellent video on the topic by Hank Green.



ANOTHER UPDATE...

And now here is Mike Rugnetta from PBS Ideas Channel



And the excellent John Oliver piece...



About 100 people sent me the John Oliver piece after we discussed Net Neutrality of EPISODE 12 OF HELLO INTERNET

MORE SOON MAYBE!?

Hello Internet Podcast

Not been very active on the blog just lately.

Guess that's because I've been busier than usual.

Plenty of new videos have been coming out - will list some of the better ones below.

Some of you may also know I've started working on a new podcast with CGP Grey called Hello Internet.

I've known Grey for a few years now.  He has even cameoed in a few of our videos, most memorably this one.



The podcast has been great fun so far (we've recorded 11 at the time of posting).

The best way to follow the podcast is via things like iTunes and RSS, etc… More details are at the Hello Internet website.

We really discuss everything - but I guess a major theme is life as YouTube film-makers.

Other important topics have included education, freebooting and plane crashes!

Our latest move has been putting the podcasts on a Hello Internet YouTube channel.

These are obviously a bit behind the general release of the audio podcasts, but another way to digest the show!



Anyway, back to may "day job".

Here are just some of the videos to come out in recent weeks.

Favourite Numbers - 7 wins again

A poll by author Alex Bellos has found, unsurprisingly, that seven is the world's favourite number!

He's released the results to coincide with his new book - Alex Through the Looking-Glass.

Numberphile had its own, less formal poll a while back.

It started with this video:



And then we harvested the stats to make this one:



Seven won that poll also.

Here are some previous appearances by Alex on Numberphile…





And his first book is Here's Looking at Euclid (aka Alex's Adventures in Numberland).

Alan's Album

Regular viewers will be familiar with the music of Alan Stewart.

Alan is a physics teacher who composes and performs music in his spare time.

I love his work and we've collaborated together on MANY videos, some of which are listed below.

Well, Alan was too humble to tell me, but he has pulled together many of his best tracks into an album on iTunes.

Here is the link.

I think it's great value.

Despite having many of them on my computer already (for obvious reasons), I downloaded the album myself last night and have been listening non-stop.

Gorgeous background music.

I especially recommend the tracks "Time Passes" and "Wait" - but maybe that is because they appear on some of my favourite videos.

(As a bonus, Alan included his Good Will Hunting inspired track, which is often requested!)
