XKCD and the Dictionary of Numbers
There are probably a few poor lost souls out there who have never heard of xkcd, so I am reposting a link to the most recent blag here as I found it simply awesome and wanted to share. XKCD is full of humour and interesting useful things including one of my favourites, the “What If?” and in particular, “Relativistic Baseball“. Science can be fun.
This post discusses a fantastic little Chrome extension written by Glen Chiacchieri, that helps put some context to the numbers you read on the web. I agree with the author who said “I don’t like large numbers without context. Phrases like “they called for a $21 billion budget cut” or “the probe will travel 60 billion miles” or “a 150,000-ton ship ran aground” don’t mean very much to me on their own.“. It is true and annoying and this little extension solves the problem nicely. This morning as I was reading through the daily news updates, I came across this: “…employing 1,500 people [≈ population of Christmas Island (nation)].”. That part I highlighted in red is the added clarification from the Dictionary of Numbers and it is very helpful.
While 1500 is not a hard number to visualize, 17Billion is. So is $12 Trillion, the current approximation of the US Public debt. Isn’t it helpful to know that $12 Trillion is also roughly equivalent to all the Fortune 500 revenues for 2011, but that is a whole other blog and conversation.
Anyway, if you are a Chrome user, I recommend heading to the Chrome store and installing this extension. I found it useful. Here is a convenient link to take you right there. CLICK ME
I also highly recommend making XKCD one of your common bookmarks because, well, science should be fun.

Because Chickens Don’t Drive Tractors
Have you ever witnessed (or been) a parent trying to explain to a 4 year old that cowboys don’t wear tiaras or that chickens don’t drive tractors? Why interfere with that creative play in the first place? Children learn through play and as we get older, we should continue to learn through play because it is the most efficient way to sync all your senses to one thought or concept. Yet at some point we arbitrarily decide to tell our children that animals can not really talk, dragons only live in fairy tales and only farmers drive tractors.
Another day, another Baktun
In spite of the best efforts of Hollywood and shock media, December 21st came and went without catastrophe or a bang, or even a whimper. Nope – aside from a raft of humorous Facebook posts, it was not much more that the scheduled winter solstice exactly as predicted. So the thirteenth long-count of the Mayan calendar comes to an end exactly 144,000 solar days (a Baktun) since the last one started, and we start counting again. This marks the end of the first Great Cycle and presumably the beginning of another. I want to believe the rest of their predictions are accurate as well, in particular the regeneration of the cosmos and the re-ordering of space and time. It couldn’t come soon enough – things have been a little chaotic lately, and not in a good way.
Really, what is wrong with people? Do we crave chaos, and drama so much that we have to twist every amazing feat of science and math into a horrific apocalyptic event? Okay, well, I guess we know the answer to that is yes. It is disappointing none the less to know that so much misinformation has clouded the fact that 3400 years ago, the Mayan people were able to build a calendar that accurately predicted every solar and lunar event in a repeating 5125 year time loop. How did we miss that? I mean as a society – how is that not the front page news?
There is a great post from NASA here with a commentary on what we should really be talking about. The world didn’t end because that was never the plan. The calendar did not end, it just cycled, like the one on your office wall does every January 1st. The next 5125 year cycle in our history is just a few days old now and we should be celebrating the coming of the new age. That is not fringe level crazy talk, that is science.
As we wind down the current version of our modern Gregorian calendar and turn the page on yet another one, I have to wonder how many other ancient sciences we have dismissed and forgotten because they were not convenient to our common religious or political views. I have to wonder if there are technologies we buried a millennia ago in favor of less accurate, but more socially acceptable ones. Maybe this Baktun we will set things right and figure it out.

Ode to the Dash8
This past week I was on a business trip that had me on six different flight segments. That in itself is not all that unusual, but three of those flights were on “Dash8” aircraft. I fly on these quite a bit and I started to wonder about the popularity of this aircraft, so I thought I would do and share some research.
I know that somewhere in my travels, I have heard that the “Dash8” (shown at left) was actually an acronym for “de Havilland Air Short Haul version 8 (D.A.S.H.8), but I have found no evidence that is actually true, however it certainly could be from the information I uncovered. Officially the plane is called a “Dash8” because the official designation is DHC-8 (pronounced: Dee Aech See DASH eight) and it has no other nickname like most of it’s predecessors the DHC-1 through DHC-7. The Dash8’s immediate predecessor, the DHC-7 was also referred to by a similar name, “Dash7” and was built as a commercial carrier with a very Short Take Off and Landing (STOL) capability. Fully loaded, it could lift off in only 610 metres (about 2000 ft) which is pretty amazing for any commercial aircraft.
The earlier DHC-6 (image on right) is more commonly known as the “Twin Otter” which will be very familiar to people who often take short hauls from Vancouver to Victoria, or from Toronto to Ottawa. These commercial “Short Hauls” are a difficult market niche for aircraft manufacturers because they have to balance agility with maintenance costs. The Dash-7 was popular at the time, but was quickly replaced by the Dash-8 due to it’s lower maintenance costs and comparable STOL capability. The Dash-8 can lift off in only 910 metres of runway (about 3000ft) which is considerably less than the comparably sized CRJ200 which requires about double that (1835 metres).
The “short haul” legacy of the Dash-8 has a familiar successful legacy in the DHC-5 (left) which people in forest fire territory will recognize as the “Buffalo” as well as the DHC-4 “Caribou” (shown below) that earned a place in history for short haul work supplying troops in Vietnam.

The Dash-8 actually comes in 4 distinct flavours including the popular Q400 which is actually the “Dash-8 type 400”, a 78 passenger version of the original. Even Westjet, who’s entire fleet consists of Boeing 737’s, just placed a conditional order for twenty Q400s to add to their fleet. Bombardier passed the 1000 unit mark of deliveries of “dash8” aircraft over 2 years ago and they still keep shipping.
An interesting note to this is that even though the Dash8-400 (AKA the Q400) is a brand new aircraft, the Dash8-100 first shipped in 1983 – Twenty Nine years ago – and many of those early birds are still in the air (I think I was on one today).
Anyway, I spend quite a bit of time in that particular make of aircraft and thought I might share some of the detail around why it is so pervasive in the short haul markets.
Hope you had fun reading about it 🙂

If you are a Disney nut, I challenge you to guess at where these photos were taken. It is a fun exercise and interesting to see where Disney puts money just to enhance the customer experience. I have posted the answers on a separate page at http://mairs.ca/tom/blog11092012pics.
