The Family That Minecrafts Together

About a month ago, JSL came home from a play-date proclaiming that he loved Minecraft.    We had intended on introducing his older brother to the game at some point figuring that he’d enjoy the building aspect.  We didn’t expect his brother to fall in love with it first.  Still, we purchased Minecraft: Pocket Edition to put on their tablets and off they went building.  After doing some research, I even set up a PocketMine server so we could all play in the same world.  (After doing this, I realized that we could just pop into each other’s worlds while we were all on the same Wi-Fi network. ) I also downloaded some maps for the boys to start them off with some creations to build on.

After awhile, I began to get curious about just what they saw in Minecraft so I installed the game and got a theme park map installed.  Soon, I was having fun on the pre-made rollercoasters.  The boys quickly jumped into my world and we all ran around in-game trying out coaster after coaster.

As I tired of simply riding what others had built, I decided to see how easy it was to build coasters.  I started to build my own coaster and was hooked.  I made a "Coaster To The Sky."  It went up as far as Minecraft would allow me to build – just about touching the clouds – and then raced down.

Every time I thought I was done, I got another idea to add to it.  Eventually, I had the cart end up dropping into a deep pit where it landed in a room floored with cake.

JSL tired of trying to build rollercoasters and asked me to install a castle map that he had found.  As he played, I jumped into his game and looked around.  When he told me that the castle was off-limits for my building, I walked into the lake and began to dig.  Eventually, I was able to build a cavern underground that was dry.  I improved on my new underground lair, but tired of the water constantly threatening to flood my land.  So I blocked off the entrance, dug a tunnel to another, drier, section, and expanded my underground operation.  At this point, I have stairs, a bedroom, a dining room, and a few spare rooms whose purpose I haven’t decided upon yet.

Even in Minecraft, JSL is a bed invader.  He decided to come into my area and lay down on my virtual bed.

The only downside to Minecrafting underground?  Heading to bed immediately afterwards and feeling seriously claustrophobic.  Every time I closed my eyes, all I could see were the dark stone walls of Minecraft’s underground surrounding me with no way out.  I felt boxed in which doesn’t help a good night’s sleep.  In the future, I need to remember to stop playing long enough for the trapped feeling to pass.  (I’ve since made my rooms larger to avoid any future in-game claustrophobia.)

Now that the boys and I are hooked on Minecraft, we can play and build together often.  There’s only one thing missing: We need to get B hooked on Minecraft also!

Are you or your kids hooked on Minecraft?  If so, what’s the coolest thing you or they have built in the game?

Vaccines and Consequences

DSC03308-C2-BLU_SmallThere’s a great debate going on in our society today over vaccination.  Some say that everyone should be vaccinated.  They point to evidence showing how vaccines prevent disease and how they are much safer than the diseases they prevent.  Others, claim that vaccines are filled with "toxins" and sometimes even raise questions about whether vaccines cause Autism.  Unfortunately, in this debate, there are some big losers: Children too young to vaccinate, people whose vaccines didn’t "take", or people with valid medical reasons not to vaccinate (for example, immune system disorders).

This "debate" has been going on ever since Andrew Wakefield published his report implicating the MMR vaccine in the development of Autism.  Unfortunately for Wakefield, his research was debunked repeatedly, shown to be an outright fraud (he not only manipulated results and took unethical steps to gather "data", but was attempting to discredit the MMR vaccine so he could market his own replacement), and his medical license was stripped from him.  Unfortunately for the rest of us, some people still hail him as a hero and decided that this debunking/license-stripping was just a witch hunt by "Big Pharma" and its supporters in retribution for telling the truth.  As the anti-vaccination crowd gained followers, outbreaks of diseases all-but-defeated started flaring up.

The debate really heated up a month ago when the public was warned that someone infected with measles visited Disneyland between December 15th and 20th.  As a result, nine people were infected.  Eight of those nine were not vaccinated.  As the days passed, the number of cases tied to the Disneyland outbreak rose to 50.  Now, they’ve topped 100.  Some of the workers at Disneyland came down with measles and Disney considered mandating vaccinations as a condition of employment.  Some people lauded this decision and some decried it as an unneeded imposition on a person’s right to choose what happens to their body.

After this, some politicians decided to voice their opposition to mandatory vaccination.  Rand Paul was notable for saying he has heard of "many tragic cases of walking, talking normal children who wound up with profound mental disorders after vaccines."  Though he didn’t come out and say it, the implication was clear.  Rand Paul was saying that vaccinating your child could lead to Autism – the major "mental disorder" that some people think is caused by vaccines.  (Autism isn’t a mental disorder, but that’s a completely different discussion.  Suffice it to say that many people think of it as one even though it isn’t.)

Finally, there was a decision from Autism Speaks.  We love supporting causes related to Autism.  Given that my son is diagnosed with Asperger’s and I’m likely an undiagnosed Aspie, it’s a cause that’s close to my heart.  However, we couldn’t, in good conscience, support Autism Speaks, because they kept supporting the notion that vaccines cause autism.  Though they encouraged vaccination on their FAQ page, they always kept wording stating that it was still possible that vaccines and autism were linked.  I was very happy to hear that Autism Speaks had come out in support of vaccinations.  There is no more quibbling or "in rare cases" loophole-wording on their website.  Instead, it’s a simple statement: "Vaccines do not cause autism.  We urge that all children be fully vaccinated."

How did we get to this point?

In a way, vaccines were a victim of their own success.  When previous generations grew up, many diseases that are now vaccine preventable were instead prevalent.  People then not only knew other people who had come down with measles, mumps, rubella, polio, whooping cough, and other diseases, but lived in fear that they or their children would be next.  Vaccines eliminated that fear.  Unfortunately, as generations pass, people with first hand knowledge of how bad these diseases are dwindle.  I myself have never seen someone with measles and only know of the horrors by reading of it.  As terrible as the accounts sound, I’m sure living it was much worse.

As the diseases faded into obscurity, the threat they seemed to possess lightened.  The horrors of weeks of coughing that prevent the person from breathing or result in vomiting were replaced with the idea that "it’s just some coughing – no big deal."  The dangers and side effects of measles (deafness, pneumonia, encephalitis, brain damage, or death to name a few) were reduced in people’s minds to "you get sick with some spots for a week and then you’re all better."  With this minimized threat in mind, the stage was set to question whether the vaccines were really needed at all and scare tactics about ingredients or disease links could take hold.

Even after all of this, though, I might agree that vaccinating your children is a personal choice if not for one simple fact: A person who decides not to vaccinate their child affects more than just their child.  If it was only a matter of opening your child to preventable diseases, I’d argue that people should vaccinate, but shouldn’t be required to.  If someone doesn’t feed their child healthy food and instead relies on a steady diet of junk food, I might argue against their choices but I’d never say they should be compelled to serve broccoli at every meal.  This is because one child’s bad eating habits don’t result in other children suddenly gaining weight.  However, when someone doesn’t vaccinate, they open the door for other people to be infected – for example, infants too young to be vaccinated or people with medical conditions that preclude vaccination.  This turns it from a "individual liberty" issue to a "community health" issue.

To those who might argue that it still comes down to individual liberty, I’d give one simple answer: Typhoid Mary.  Mary Mallon had a problem.  Every where she went, she would find work as a cook until a typhoid outbreak occurred.  Then, she would leave town quickly, setting up shop somewhere else.  Eventually, it was discovered that she was a carrier for typhoid.  She carried the disease, but didn’t get sick from it.  Unfortunately, the people whose food she prepared weren’t so lucky.  She was held in custody and told she could go if she didn’t cook for people again.  She initially refused to agree to this or even to take basic steps to improve her hygiene, but finally she agreed to the terms and was released.  It didn’t take long before she began cooking again under an assumed name and not long after that more people got sick.  Two people died as a result.  Mary was again taken into custody, but this time she remained in custody for the rest of her life.

Some people might decry the government for infringing on her right to life, liberty, and the pursuit of happiness (her chosen career of cooking), but the problem with this argument is that rights have limits.  The common expression is "Your right to swing your fist ends at my face."  One cannot simply do as one likes, ignoring all consequences, and chalk it up to "rights."  Just as with Typhoid Mary, people who don’t vaccinate puts others at risk.  In the case of Typhoid Mary, it was by direct infection.  In the case of people who don’t vaccinate (for other than valid medical reasons), it is because they weaken herd immunity.

A quick aside for people who don’t know what "herd immunity" is.  Diseases spread from person to person.  They survive not by killing their hosts, but by keeping the host long enough to spread them to as many people as possible.  With the natural immunity that people obtained from surviving the diseases, there was a group of people that the diseases couldn’t cling to.  Unfortunately, this number was too low to impede the spread of the disease.  In addition, contracting the diseases might mean you’d get the immunity, but you would also risk horrible side effects or even death.  With vaccination, the number of people with immunity climbed to such an extant that diseases found it impossible to find someone to use as a ride.  With their paths to spread limited, the diseases were held back or even (in the case of smallpox) eliminated.

Herd immunity protects those who can’t be vaccinated due to age or illness.  It also protected in case someone’s vaccine didn’t take.  (Vaccines aren’t 100% protection.  Even 99.99% protection means that a lot of people will get the shot but could still get sick.)  When the first anti-vax folks decided not to vaccinate, their kids didn’t get sick because of herd immunity as well.  Herd immunity was able to withstand a few people not getting protected.  As the numbers spread, though, new paths opened up for the diseases.  They found themselves able to spread to more people again.  Thus, we get a resurgence in measles, whooping cough, and other vaccine-preventable diseases.

And here we come to the consequence portion.  When someone chooses not to vaccinate, they not only make a decision that affects their own child, but they make one that opens thousands of other people to possible harm.  Not vaccinating is not only listening to bad advice (vaccines have proven their effectiveness many times over) and is not only bad risk assessment (the risks of vaccines are minimal and the risks of the diseases they prevent are immense), but it is putting others in harms way in the name of exercising your own liberty.  I wouldn’t condone someone driving drunk because "they should be allowed to drive however they like" because doing so puts more than the drunk driver in danger.  Similarly, not vaccinating puts many other people at risk – as the Disneyland outbreak demonstrates.  Sadly, it might take a high profile outbreak like this to give some people some perspective.

As a parent and as a human being, I urge parents to vaccinate their children.  If you have concerns, talk with your doctor.  Don’t listen to celebrities or people whose research was shown to be a fraud.  Don’t listen to people who talk about "toxins" like formaldehyde in vaccines (you get more by eating a single apple) or who rant about "Big Pharma."  Talk to a trained medical professional to get the real story and then make sure your child gets vaccinated.  Don’t let the diseases spread.  Don’t let more people get sick and die.  Let’s get herd immunity working again so more diseases can join smallpox and be eliminated for good.

Sick Of Winter

We’ve had two snowstorms in two weeks totaling around 30 inches.  We have ice dams across both roofs with possible water coming in the house.  When it isn’t snowing, it’s freezing cold.  Actually, check that last one because it’s freezing cold when it’s snowing also.  Oh, and there might be more snowstorms headed our way.

I’m sick of shoveling.

And, yes, the icicles might be pretty…

… but then they drip all over my driveway and make us nearly break our necks trying to go to our cars.

In short, I’m sick of winter.  I can’t wait for it to be over with.  I want the warmth and green of spring.  I want to be able to leave the house without using coats, hats, gloves, boots, and STILL being cold.

How long until spring again?

38 days?

So close and yet so far away.

Are you sick of winter yet?

Extreme Geekery: Give Me A Lever Long Enough…

LeverArchimedes once said "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world."  He was waxing poetic about the power of the lever.  The lever is one of several simple machines along with the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.  These machines can help to perform feats that a man acting alone using only his own strength couldn’t hope to achieve.  They can also be combined to increase the machines’ abilities.  Of course, I don’t think Archimedes really meant that one could set up a lever and move the entire Earth.

But could you do this?  How long would the lever need to be?

Obviously, there are some stumbling blocks to our plan.  First of all, there’s no ground in space to position the lever’s fulcrum.  Even if we made a giant lever and somehow put it against the Earth , pushing down on one side would cause the entire contraption to drift through space.  There’s also the problems that gravity would cause – the gravity on the lever close to the Earth would be more than the gravity further away.  What’s more, unlike a lever on Earth, we’ll be battling against the gravity of the Earth orbiting the Sun, not an object resting on the Earth.

Houston-Problem

All of this could, at least, seriously mess up the calculations for how long our lever would need to be or, at worst, make the whole affair pointless.  Since there’s no such thing as "pointless" when it comes to Extreme Geekery, .  Let’s simplify things, by making two assumptions.  First will be some "ground" and Earthlike gravity.  Our fulcrum will rest on the "ground" and will push up against the Earth attempting to lift it as if it were just an extremely large rock.  The second assumption is that there isn’t any other source of gravity to mess things up.  We’re ignoring the Sun, other planets, the Moon.  Everything.

So, how long would a lever need to be to move the world?  The formula for this is quite simple:

F1 * D1 = F2 * D2

In other words, the force applied down (F1) times the length (distance) of the "pushed down" portion of the lever (D1) is equal to the force upward on the other side of the lever (F2) times the length of that side of the lever (D2).  We’ll position the lever and fulcrum so that the "Earth side" is under half of the planet.  Initially, you might think that this means that the Earth side of the lever is the radius of the Earth.  Don’t worry.  I did too.  I figured out all of my calculations before realizing the truth.  (The good news is that I had to do more math.  This is always good news to a math geek.)

Yay-Math

The radius of the Earth at the equator is 6,378 km.  The radius from center to pole is 6,360 km.  The rest depends on how inclined the lever is, but let’s say it’s raised so that the it is up 25% of the center-to-pole radius.  We need to figure out what side C is.  Easy enough.  Using the formula A2 + B2 = C2 gives us a result of about 6,573 km.

The weight of the Earth is easily Googled: 5.972 x 1024 kg.  This only leaves us the force pushing down on the other side.  Given that Archimedes said he could do it, I’m going to say that only one person should attempt it.  No cheating and gathering an army or pushing on it with rocket thrusters.  We’ll do this see-saw style and sit the person on the other end of the lever.  We’ll have the person be 100kg – perhaps slightly overweight but not unrealistically so.

Now how long is the "pushed down" side of the lever?  Well, we have:

D1 * 100 kg * 9.8 m/s2 = 5.972 * 1024 * 9.8 m/s2 * 6,573 km

(Side note: In case you’re wondering where those 9.8s came from, force equals mass times acceleration.  F = ma.  This means that the forces we need for each side of our lever equation are really the weight of our objects times the acceleration – our faked Earth gravity down.  Also, yes I know they cancel each other out, but I’m including them in there for completeness.)

Simplified, this gives us a lever distance of 3.93 * 1026 km.  That seems pretty long, but how long is it really?

Light is the fastest substance known.  The speed it travels at can’t be matched by anything we know of.  That’s why we measure distances in light years – or the distance that light travels in a year.  One light year is 9.46 * 1012 km.  This means our side of the lever would need to be about 4.15 * 1013 (or 41.5 trillion) light years long.  How long is this?  Well, it’s certainly longer than the Milky Way.  That’s 100,000 light years across.  It’s even bigger than the diameter of our local supercluster of galaxies.  That’s 110 million light years.  In fact, our observable Universe is only 45.7 billion light years so our lever would need to be over 908 times the length of the known Universe.

That’s one big lever.

Ok, so one person probably couldn’t do it alone – even by Extreme Geekery standards.  But what about the power of teamwork?  If every human on Earth got together and sat down on the lever, how long would it need to be to move the Earth?

All humans together weigh 632 billion pounds or 286.67 billion kg.  Plugging this into our formula above means that our lever would need to be 1.37 * 1017 km or about 14,474 light years.  This distance is much more reasonable.  Yay teamwork!  Still, maybe we could improve the results.

All of the biomass on Earth (except bacteria – those guys claim to have lost their invitations) hopped onto our galactic see-saw now.

Bacteria

Totaled up, Earth’s biomass weighs 560 billion tonnes or 560 trillion kg.  This translates into a lever of 7 * 1015 km or about 741 light years.  Even better still.

Of course, even a "mere" 741 light years is a long distance for a lever.  As much of a genius that Archimedes was, he might have overestimated himself when it came to levers.  Unless…

Soft Cookie, Warm Cookie, Cookie On A Shirt

After my "Soft Cookie" post the other day, I thought I was done what that parody song.  However, I began thinking of other images I could base off of it.  Eventually, I came up with this:

cookie_song_mosaic_web

I liked how it came out so much that I thought "That would look good on a t-shirt."  You know what?  It does!  Here’s the link in case you want to buy a t-shirt.

On a related note: Did you know I had a Zazzle store?  I didn’t.  I opened it awhile back intending to sell products with some photos I took but never did anything with it. I’m resurrecting it to offer my "Soft Cookie" products. Does this make it a Zombie Zazzle store?  (The things you think of when you’re writing your post at 12:40am.)

The only bad part about this graphic? It’s making me hungry for cookies! I think I need to run to the store tomorrow.
