Yes, you do weigh less at the Equator, and here's roughly how much

Earths Gravity
You can change your weight in many ways.  But, there is one way that doesn't require doing anything more than just travelling North or South.  Most dramatically, your weight is different at the Equator than it is at the North Pole.  This is due to the centrifugal force of the Earth's daily rotation.

The Earth spins one full rotation in a period just under 24 hours (kinda).  At a spot that is one inch from the North (or South) Pole, the speed of the ground as it rotates around the axis is literally just over 1/4in per hour.   By comparison, a common snail can slither 1837in per hour.  However, at the Equator, the speed of the ground as it rotates around the axis is a whopping 1,036 MPH!  This is faster than the Speed of Sound (761.2 MPH).  Thankfully, the laws of nature do a great job of making sure we do not notice such things as we walk about in your daily lives.

Even still, that is fast enough to notice the effect of the centrifugal force of Earth's spin on your weight.  Basically, you weigh less at the Equator than you do at the North Pole.  Your mass doesn't change, of course.  It's just that the pull of Earth's gravity is slightly mitigated by it's rotation about its axis.

That said, there are many factors that affect the local gravity.  The problem is that gravity itself is generally measured in terms that are meaningless to everyday life.  So, when an online local gravity calculator tells you that your local gravity in meters per seconds squared, that isn't all that helpful in finding out how much more or less you'll weight somewhere else.

I've created a simplified calculator as a spreadsheet .  It will tell you how much you'll weigh at any latitude based on your current weight at your current latitude.  The calculations on the spreadsheet are rough.  They do not take into account many factors that might affect your weight, nor are they precise enough for serious scientific studies.  However, they are close enough to satisfy whatever curiosity you might have.  As such, use the spreadsheet for entertainment purposes only, and have fun seeing how much less you'll weight at particular latitudes!

Updated States Travelled List

I've travelled to a few more places in North America recently.  Here's my updated map of US:

Stopped in L.A.

While running around L.A. with Allie after SOLIDWORKS World 2017, I was approached twice over the weekend in early February.

We were queued for a ride at an amusement part.  The guy behind Allie and I got my attention and asked, "Are you in a recent movie?  I feel like I've seen you somewhere."  Now, if I had been such a D-list star that someone kinda recognized me but didn't know for sure, I might have been mildly insulted.  But, as it turns how, I am not a star.  I'm just a guy that gets mistaken for other people from time to time.  Instead, I'm mildly amused.  Sorry, no point in getting a photo with me or having my autograph.
The next day, Allie and I were walking along Venice Beach.  We had just spotted Emma Roberts on the walk down to the beach, but she looked busy on the phone as she rushed into a wardrobe trailer.  Anyway, down on Venice Beach, this one guy road up to us on his bike.  He didn't recognize me so much as he recognized the shirt I wore.  It was a t-shirt from SOLIDWORKS World 2017.  He is a SOLIDWORKS user who didn't get to go to the conference this year even though it was in L.A.  The conversation was pleasant, but soon enough, Allie and I were on our way down the beach again.

Of course, as an employee of Dassault Systemes that supports the development of SOLIDWORKS products, I expect to be approached at the SOLIDWORKS World 2017 conference.  However, SOLIDWORKS is well enough known that anyone wearing the company shirts or even t-shirts will be approached from time to time just for that alone.  I actually try to avoid wearing the actual company shirts when travelling or attending any nonwork event.  You'll never know when someone will approach you to talk shop, not that I mind all the much.  It's just nice to keep the universes separate when I'm out with my wife or focused on getting somewhere.

I learned a little bit about travel this weekend

Allie and I went to the Southern New England AAA Travel Show this weekend at Twin Rivers Casino.  I learned that for some types of trips, it pays to plan early but book late.  Other types of trips, it pays to book early, period.  Balancing flights with the rest of the trip seems to be a bit of an art form.    We didn't go to the expo to book a trip.  We just went for ideas...and ideas are to be gained!

There were a lot of travel vendors at the expo, and a lot of AAA agents available for booking trips immediately. One lacking thing I noted is that most of the vendors didn't have swag.  The ones that did pretty much just offered candy.  A couple offered pens.  Eh.

Some people have goals or accomplishments where they've been/plan-to-go to every country.  My sites are not so grandiose.  I simply want to at least visit each of the continents.  So far, I have Asia, North America and Europe.  That leaves South America, Africa, Australia and Antarctica.

Great time at Islands of Adventure

Allie, I and other friends had a great time at the SolidWorks World 2013 Special Event at Universal's Islands of Adventure at night. Even though time was short, we did a full circuit of the park, enjoying the Harry Potter ride, Jurassic Park ride, Spider-man ride, Mind Eraser ride and The Hulk rollercoaster. The food was great too!

Meeting Mike Rowe

The Joke
When travelling across country late last year with my wife, I discovered a section of our hotel store at the Grand Canyon that was dedicated to Dirty Jobs with Mike Rowe. There was a foam board cut out of Mike Rowe’s image. To joke with my wife, who loves Mike Rowe but who never found her way into the store, I took a photo of me with the 2D cut out. The joke turned out to be so little, Allie forget all about the photo within a couple of days.

Irony a few months later
In a bit of irony, I actually did meet Mike Rowe at SolidWorks World 2012 earlier this year. Yes, he graciously took his photo with me. Can you tell which is the real Mike Rowe?



SolidWorks World 2012 is a design conference dedicated to 3D CAD related products and services for engineering and similar fields. The conference happened to fall on Valentine's Day this year. It was in San Diego. This means, I (and many attendees) were away from our spouses on Valentine's Day. I asked Mike Rowe if he would write a Valentine's Day message to my wife (an autograph written to Allie). He signed my conference badge. I'm not going to show it here because its my gift to my wife. It is an autograph that will never be sold, and it's up to Allie to show it off!

I thanked Mike Rowe a bit too much and then told him that my wife and I have been fans since he was on Evening Magazine in the San Francisco Bay Area. He looked at me surprized, if not a tiny bit consternated.

On Stage
On stage at the conference, Mike Rowe talked about the need to bring recognition and honor back to the blue collar trades (plumbers, electricians, etc). He founded mikeroweWORKS for this purpose and to help people connect with each other in the trades.

Alaska Cruise Day 7: Not Alaska (B.C.)

Day 7 of our Alaska cruise was highlighted by a visit to Victoria, British Columbia. Many people don't realize that the name Columbia was used by our North and South American forefathers to name a bit of land that they really didn't have a name for. Columbia is the "poetic" name for the Americas. There's also Washington, District of Columbia (Washington, D.C.) and the actual country of Columbia.

Victoria is a very nice city with many interesting buildings, good food and they freely take U.S. dollars (1:1 with the Canadian dollar these days).





My In-laws liked it a lot. We had a relaxing time, just walking around without too much of a schedule to worry about. We had a great dinner at a local steakhouse. There was this Celtic themed store with some of the highest quality clothes I've seen (and the prices to match). I even have a video around somewhere of Darth Vader playing the violin (street performer).

The vibe in Victoria is definately different than Vancouver, B.C.

One of the reasons we chose to take a cruise with Norwegian is that the cruise starts and finishes in Seattle, WA (within the borders of USA). Many cruises start in Seattle, but then end in Victoria. That means we'd have to take an international flight home; a painful experience which I am always more than happy to avoid.

So, even though Norwegian wasn't everything we expected it to be, it was everything it needed to be. I guess that's not a great endorsement, huh.

Overall, the trip was enjoyable. Some pluses (many of which cost more $$$) and some minuses (many of which were part of the cruise package for no additional $$$). We did our trip to Alaska. We did our first cruise (and prolly last, at least for a long while). We took my In-laws on a big vacation and had a lot of quality time with them. And, I got to see my best friend and his family before and after the cruise.

Alaska Cruise Day 6: Ziplining

Day 6 of my family's Alaska cruise was marked by a visit to Ketchikan. Suprizingly enough, we didn't spend much time in Ketchikan itself. Our excursion took up almost all of the time.

I did the ziplining canopy tour in the rainforest. By an amazing coincidence, Allie took her parents on a nature walk excursion that was run by the same operation on the rain forest floor. So, while I was zipping around overhead, they were walking on a guided tour below. Allie said she kept an eye out for me, but we weren't in the same part of the forest at the same time.



They got to see a bald eagle, owl, bear markings on a tree, a canoe being made (in progress, not from start to finish), and other natural or native items.


I was zipping around the canopy with a group of people, most of which have never ziplined before. It was a lot of fun. I haven't developed the photos from this adventure on my disposal camera yet. Hopefully the film is still good after all this time (2 years). I do have this shot taken by an automatic "ride" camera.


Note the gratuitous fist pump. :)

The excursion took up so much time in the trip to a from the dock and on the adventure itself, we didn't get a chance to check out anything in the town of Ketchikan itself.
