Holiday on Mars… not in my lifetime

It’s fun to think of space tourism, now that the first civilian visit to the space station has happened. I’d love to spend a few days in space someday. Knowing my vertigo issues on spinning rides, I’d probably spend most of the trip with motion sickness and it will be far less fun than I imagine… but I want to try! I want to experience weightlessness for a few days, and to be an astronaut.

But that’s just for a few days. There are some serious issues that astronauts face when going to space for long periods of time.

“Astronauts on space missions suffer from balance problems, visual disturbances, ‎damage to the heart muscle and bone loss.” – The Dangers of Zero Gravity

These get more and more serious the longer you spend in space. Especially effects to our vision.

“…if we want to think about colonisation or extended stays on Mars, we’re going to have to consider blindness as a potential complication.

Right now, there are no solutions for how to treat or prevent fluid build-up in space, and with the brain damage that’s also expected to come from long-term spaceflight.” – Space Could Leave You Blind, And Scientists Say They’ve Finally Figured Out Why

Basically, a several year journey to Mars will be extremely detrimental to the health of anyone who makes the journey.

The next steps in getting there?

1. We need to find out if we need to replicate a full 1G environment or if long term travel at a less gravitational force will be required to rid ourselves of these health issues for long term space travel.

2. We need massive rotating space stations that are designed to provide us with some gravitational force.

3. We need to build these and experiment with them as we just start thinking about colonizing the moon.

4. We need a working moon colonization before even thinking about colonizing Mars.

This will take decades and decades.

I will be 100 if I can make it to 2067… it doesn’t matter how close they are to moon visits by then, and how advanced longevity Science is, I’ll be in no shape to make the moon journey, much less a several year trip to Mars.

It’s fun to think about space holidays like we see in the movies, and who knows, maybe in 100 years that will be possible. But without some significant scientific leaps in technology, space tourism in my lifetime will only go as far as the international space station or maybe a very short moon landing… I’ll just need to save up a few million dollars for the trip before I get too old. Because in my lifetime a trip beyond the space station (which might be affordable in my foreseeable future) will still only be the holiday destination of millionaires and billionaires. My feet will never touch the moon, much less Mars.

That said, if I had the chance to go to the Moon, I’d go!

Mars on the other hand? Not a chance of this happening. This will likely be an adventure opportunity for my grandkids or maybe great-grandkids. By then there might be a technology that allows faster space travel. Maybe they will take a picnic lunch on a trip to Saturn’s rings. It’s fun to imagine space travel that simply isn’t possible today.

The Jetsons, created in 1962 was supposed to depict our world a hundred years in the future. I don’t think we’ll be living and traveling like them in 2062. Technology does not advance as fast as our imaginations.

Door to door religion

When it comes to organized religion, I struggle with the concepts of an afterlife. I have yet to hear a description that makes me think, “That’s how I want to spend an eternity.”

I have a great way to quickly end the conversation when a Jehovah Witness knocks at my door. My usual response to them is, “I’m comfortable with my relationship to God.” If they say anything else to me I repeat that statement. Only once did the conversation continue and in that case I simply asked, “Are you comfortable with your relationship with God?” And with a ‘Yes’ response, I said “Me too.”

Works every time. Conversation over. They leave happy, I’m happy they left.

The summer before the pandemic I had a Jehovah Witness couple come to my door. I did something dangerous, I played along. This is dangerous because once you engage in a conversation, you are likely to get callbacks. More visits because you show promise. But when I was done, I was very doubtful of another visit.

I talked about millions of years of dinosaurs, and how insignificant human life has been in geological time… and how much less significance the earth has in the universe. I spoke of the injustice of a God who didn’t share his views equitably around the world, allowing false Gods to reign in different parts of the world, condemning people who never heard of Him to hell.

And then they brought up the afterlife. At this point I clarified, “Is it correct that you believe heaven will be here on earth?” And after their response was ‘Yes’ I said, “And you’ll all be naked.”

They looked at each other puzzled, and I continued with this line of thinking: When the rapture happens, and heaven happens on earth, you’ll have the clothing you own and nothing else. There will not be anyone in sweatshops making T-shirts and running shoes. Unless God is in the manufacturing business, clothes will wear out, unless you think heaven is some sort of magical cartoon land, and so eventually you’ll all be naked. Don’t worry, there won’t be any jealousy or vanity, it is heaven after all, but you will be naked for eternity.

The conversation ended soon after. They were pleasant and ended with “God bless you.” My response to this was “By all means, may God bless you, I’m fairly certain after our conversation, your God won’t be blessing me.” A meek smile was the only response.

I don’t know what got over me that day, but I’ll go back to my usual response from now on. Still it was fun to mess with their minds a little. Some might think it mean, but I didn’t go knocking on their door trying to indoctrinate them with my views, they came to my door to do so to me.

I guess I can’t be saved.

All the world is an improv stage

Think of the roles you play in life: A child, son or daughter to parents… Sibling. Student. Friend. Employee/Boss. Boyfriend/Girlfriend. Husband/Wife. Parent. Caregiver….

We take on so many roles in our lives. And when we take them on, we do so without an instruction manual. We play the role, not knowing how to really do it. You can be trained for a job, but not for every scenario you face. You can model yourself as a parent based on what you’ve seen other parents do, but your child will challenge your skills in unexpected ways.

Every role you take on will put you into situations where you are going off script, you are improvising to the best of your abilities. Sometimes nailing the role and making great choices. Sometimes bombing and making decisions that make the role harder.

All the world is a stage, and we are all actors, playing parts we learn as we play them. Some people play certain parts really well, while they flop in different roles. Not too many people, if any, are able to play each of their roles without struggling somewhere. We admire those that put on a show and do things really well. We complain about those that can’t or don’t play their role well. We often lack confidence that we can do our role well enough.

We are far more critical of how we play our roles compared to others. We often feel like we are the only ones acting… everyone else has a script. But there is no script. There is no one path, improv doesn’t work if everything is set up. It has rules to keep going well. It’s better to support the actors around you than it is to cut them off. It’s better to understand that you share the stage than trying to go solo.

It’s not about getting everything right. It’s about helping others when they are lost for their lines, their roles. It’s about sharing and laughing. It’s about enjoying the performance, even when it’s challenging. It’s about taking on new roles, and trying new things.

The world is your stage. The play is your playground. Improvise your roles as best as you can. And remember that others are improvising theirs roles too. Work with your fellow actors to create the best performance you can. But remember it’s all an act, and if you aren’t playing a role that works, change the role or change the way you act in it. All the world is an improv stage, and so you get to write the script as you go. Enjoy the performance, you only get one.

Everything Everywhere All at Once

I saw this film last night. Funny, dark, and thoroughly enjoyable. It’s hard to describe the humour. I think if Quentin Tarantino, Mell Brooks, and the Monty Python crew all got together and got high, this is the movie they would write and film.

I was driving home and laughed out loud at the origins backstory of hotdog fingers. Yes, you read that correctly.

This movie is an epic journey, and it will gain a cult-like following of fans. It definitely won’t be for everyone, but if you love an action film, filled with dark humour, you won’t want to miss this movie… And don’t wait for it to start streaming, go see it in a theatre to truly appreciate other people laughing at the absurdity of some of the scenes.

I don’t usually enjoy watching movies a second time. It takes a special movie for me to re-watch. This will be one of those movies.

Everything Everywhere All at Once gets a 10/10 from me.

Fun with Math

Take ANY number, subtract the digits in that number, and the answer is divisible by 9.

14… 14 – 1 – 4 = 9

25… 25 – 2 – 5 = 18

36… 36 – 3 – 6 = 27

49… 49 – 4 – 9 = 36

1,234… 1,234 – 1 – 2 – 3 – 4 = 1,224

And you don’t need your calculator to figure out if 1224 is divisible by 9, it is. How do I know? Add 1 + 2 + 2 + 4 together and if it’s 9 or divisible by 9, then the number is also divisible by 9.

7,692… 7,692 – 7 – 6 – 9 – 2 = 7,668

And then 7 + 6 + 6 + 8 = 27 which is divisible by 9 so 7,668 is divisible by 9 (= 852).

I love Math.

Culture of change

Connecting with colleagues in the world of online learning, I realize that we live in a unique world of change. If I ask most school principals that work in traditional schools about student funding, and funding policy, few would know much in this area. If I followed up with audit questions, many would know even less. But in over a decade of working in online learning. I’ve dealt with audits and funding policy changes, and constant shifting of expectations and goal posts… and so have my online colleagues in different districts.

Many of them wear several hats (I’ve run 2 schools for years, and 3 schools for a year and a half.) Some are Vice Principals, some are district principals. Some are responsible for alternate students, others adults, still others both. Many got a good dose of ‘other duties as assigned’ especially during the pandemic. Most saw dramatic increases in students because of the pandemic.

Change, change, change.

When I’m around this group, I’m connected to people that know my job better than almost every principal in my district. I hear about the challenges they face and I totally get it. And more than anything I see dedicated educators who face constant changes and are always thinking about the impact of those changes on kids.

It’s really special to spend time with people who understand how to not just cope with change but to strive in it.

Breaking bread

Last night I had dinner with online principals from other districts in the province. We are on the online principals association executive, and this was the first time we met face to face in over 2 years. Yes, we are all comfortable with technology and communicating online. Yes, we’ve connected online several times over the last couple years. But there is something really special about connecting face-to-face and breaking bread.

Maybe in a decade or so we’ll be able to meet virtually online and have a full out of body experience, with avatars sitting next to each other and each of us wearing googles that allow ourselves to see the visited environment from a first person perspective. We might even be able to simulate the experience of shaking hands. At some point in the future we might be able to have an experience that feels just like we are together when we are not.

These virtual world experiences are something I look forward to. I’d love to sit in a room with my parents more than once a year. But I won’t be able to taste my mom’s cooking. I won’t be able to break bread. So while the promise of technology advancing so much that we can better simulate being together in a virtual room when we can’t be together is very promising, it won’t replace actually getting together in every way.

I still want to connect with people face-to-face when I can. Not just to eat with them and to taste good food, but to have that human connection that has been mostly absent for the past couple years. I’m excited about technology being able to get us together in new ways, to improve the opportunities of connecting in more meaningful ways, but not to replace actually getting together when we can.

On the stage

Last night my youngest performed her ‘Set of 5’. Her and 3 other classmates choose 5 songs to sing and do a patter in between them. The songs and stories are personal and raw. They can change the lyrics of songs to better tell their story.

There is something really special about watching aspiring singers and actresses open up and share a part of themselves on stage.

I don’t know how they do it? It’s so far off of what I’d feel capable of doing. First off, I really can’t sing. But beyond that, the idea of getting on a stage and confidently expressing such confidence and candour… it’s all too much for me.

They on the other hand, they shine when on stage. They connect with the audience, incite laughter and tears, and take us on a wonderful journey. All the world may be a stage, but it takes a special kind of person to get up on a stage and give a truly great performance.

Time dilation

Yesterday I experienced a bit of a time warp. My morning went a bit slow, both in my productivity and in how long it felt. After lunch it felt like everything was thrown my way, and I was constantly on my ‘to do’ list, which seemed to be filled with things that took longer than they should.

At one point a package arrived, and I thought I’d take a break and take it to the teacher who ordered it. When I passed my grade 9 classroom it was empty, and I wondered where they were? As I learned, they had left for home. I thought it was about 2:30 in the afternoon and it was actually 3:50. It was almost an hour and a half later than I thought!

I’m always amazed by experiences like this. How can one hour of busy work or fun disappear, and another hour of slow work or boredom feel like an eternity? Just like actual time dilation is about time being different based on relative velocity, it seems as though we can experience this based on the velocity of our thoughts relative to actual time.

I also wonder about how relative time is based on our age. Five years is half of a lifetime to a 10 year old, but just 1/11th of a lifetime for me. Does my perception of time change with age? Does the importance of events alter because of the relative time of the experience compared to how many more experiences the event is compared to?

And what makes a single day feel both short and long at the same time? It’s early April, and I already know that the school year will be ending before I realize it. I’ll be swept up in all the things that are coming up, like report cards and grad prep, and suddenly I’ll be saying goodbye to a whole group of students. On that journey I’ll have long and short days, but looking back at the end of June, I’ll think the days from now until then just breezed by.

It’s not just a day in time that dilates, but weeks, months, and years too. It just seems strange… We want to fill our time with activities and events that are enjoyable and thus tend to go by faster. So, we are literally speeding up our lives. But the alternative is to spend a perceptually longer life that is less busy and enjoyable. Is one of the goals of life to have it feel like it’s going too fast? Or is this just an outcome of a good life?

One cation I think this brings attention to is that if time is going to race by, we should at least do our best to make it joyful and not just busy. Because time can also race by when we are just busy, but to what end?

The answer doesn’t seem right

Back in December I shared that we really don’t understand exponential growth. Well I’m about to share a question with an answer that will boggle your mind. All I ask is that you make a guess at the answer before looking at it.

Imagine we get every single human being on earth to play a ‘winner play on’ game of rock-paper-scissor. First, let’s round up the population to 8 billion. And let’s assume every one of them can play.

A game of Rock-Paper-Scissors with 8,000,000,000 people.

So the first round will be 4 billion pairs of people, with 4 billion losing, and 4 billion winning and moving on to the next round. The question is:

How many rounds of rock-paper-scissors will the winning person have to win consecutively in order to be the world champion?

Guess.

I’ll give you a hint: it’s less than 100.

What do you think?

Here is the answer.

Well, what if we added another 1/2 billion people? That would be 500 million more players, or 8.5 billion total. The answer would still be the same!

Hard to believe. It’s so difficult to wrap your mind around needing this many games to whittle 8 billion people down to one winner. It just doesn’t seem right… but it is.
