Friday Funny: Tour de Quarantine: Stages 6 – 10


David Meego - Click for blog homepageFollowing on from last week’s Friday Funny: Tour de Quarantine: Stages 1 – 5, we have the next five stages for your viewing pleasure.

While none of us like the need for isolation and quarantine, it has given many creative people too much free time and the result is the many really funny videos are doing the rounds on the interwebs.

This series tickled my fancy as each year I become a Tour de France widower as my wife, Jennifer, watches the race footage every night. Credit to Brad Sohner on YouTube for making us laugh.

Friday Funny: Star Wars IV – A New Hope: Scene 38 Reimagined


David Meego - Click for blog homepageEarlier this month (a few days after May the Fourth) the team from the YouTube Channel FXitinPost released an unofficial short of their version of the lightsaber battle between Darth Vader and Obi Wan (Ben) Kenobi on the Death Star as Luke, Leia, Han, Chewbacca (RIP: Peter Mayhew) and C3PO & R2D2 escape.

If you have seen the movie Rogue One, the ending scene finally shows why Darth Vader was feared. Watching the original version of the fight between Vader and Kenobi, the fight seems pretty boring by today’s standards. This fan created reimagining is amazing and a much more in line with the recent movies.

Friday Funny: The Order of Operations is Wrong


David Meego - Click for blog homepageLast week, I mentioned having a chat with Jim in the US about Order of Operations and algebra mathematics problems. He sent me a link to a video on Order of Operations title “The Order of Operations is Wrong”. The video description does go on to explain that Order of Operations is “Morally Wrong, that is…”.

I actually agree which much of what the video says and wanted to clarify what I see as the issue with blindly (and sometimes incorrectly) following the Order of Operations mnemonic that you were taught at primary/elementary school.

Friday Funny: Fruit themed algebra maths puzzle


David Meego - Click for blog homepageThis week started for me with a very interesting phone call. It was from a gentleman from the United States looking for algebra based educational materials. I thought he must have the wrong number and forwarded him to Winthrop Australia (a Perth based computer firm associated with the University of WA)*. I thought that they would be able to assist due to their association with the university and education.

Anyhow, they sent him back to me and during the second call, I realized that the caller, Jim, was talking about my Friday Funny posts which sometimes included algebra problems! Once we had worked out the common ground, Jim and I had a long chat about Order of Operations and adding negative numbers. Jim is part of a Facebook group and often posts puzzles for the others to solve.

He found the same problems that I found. Many people don’t know about Order of Operations, or do know, but cannot implement them correctly or just cannot add negative numbers. For more information see: Answer: Only for genius ?? 3 – 3 x 6 + 2 = ??.

That phone call prompted me to find a new graphic algebra problem for you to solve….

Friday Funny: More on AFL: Australian Football League


David Meego - Click for blog homepageToday for the Friday Funny article I have decided to revisit a topic I posted about three years ago…. Our national sport: AFL or Australian Football League or Australian Rules Football or Aussie Rules or just Footy.

I am originally from the UK and was only introduced to AFL when I arrived in Australia as a 13 year old in 1981. I have never been a huge sports fan, but enjoy watching skilful athletes playing regardless of the discipline or code. FYI: We have seven football codes in Australia: Aussie Rules, Rugby Union, Rugby League, Football (Soccer), Gird Iron (American Football), Gaelic Football and International Rules (a Gaelic football & AFL mashup).

I wanted to share AFL with you again after my recent trip to Fargo when I showed some videos to one of the staff at the hotel and he was amazed by what he saw. It seems that many people outside of Australia mistakenly believe that Rugby is the biggest football code in Australia and don’t realise that AFL is completely different from Rugby (even if the ball is a similar shape).

Friday Funny: Life Size Lego Technic Bugatti Chiron


David Meego - Click for blog homepageI believe that by now most of you should know that I love Lego. I have always had Lego in my life as a kid and also as an adult.

In recent years I have used Lego Mindstorms to design and build robots to help me be a better robotics mentor for the school my son’s went to.

Even though both my sons have left the school for university, I still mentor for the robotics club and am also on the Robocup Junior Australia Western Australia committee.

Friday Funny: It’s true, Toilets do flow the other direction in Australia


David Meego - Click for blog homepageFor many years, when I have visited the US for conferences, there is always someone who makes a joke about the toilets flowing in the other direction in Australia. I am not talking about back up (unless there is really bad flooding), but the direction of the rotation as the water flows down.

The answer is yes, it does flow the other way. It is called the Coriolis Effect or Coriolis Force after the French Scientist, Gaspard-Gustave de Coriolis who wrote a paper on the topic in 1835.

Friday Funny: Polygons, Bananas and Clocks Maths Problem


David Meego - Click for blog homepageAfter all the fun on Twitter after the last Friday Funny: Sporting Maths Puzzle, I have found another one to challenge you with.

This one also comes from the Book of Face and showed up because some of my friends had commented on it.

Now, I will not say whether their answers are correct or not because last time I missed something and so what I thought was the answer was incorrect initially.
