QUESTION YOUR WORLD - the amazing BRAIN!!

How many different brains were involved in making it possible for you to read this blog entry? Whew! That's a tall order to even look into!

Think about all the amazing things the human brain has done, yet it's a pretty small organ. The brain takes up about 2% of your body mass, that's it! Despite its small size it sure does carry out a lot of vital functions that keep you going — such as: breathing, eating, walking, thinking, sleeping, sitting, showering, brushing your teeth, and so on...

The brain also uses up about 20% of the oxygen we take in!
On average a human brain is about 77% water!
The brain also works on about 20 watts of power (the same as a laptop or the bulb in your fridge)!
Need more brains? Here's more info on the brain!!
STILL need more brains?? ...even more info on your brain!!!

So since these things are so important, make sure you keep your brain safe!! Helmets are our friends!!

Question Your World - Question Your Coffee

Did you have any coffee today? A lot of people did. The United States moves about 400 million cups of coffee every day! Everything from intricate gourmet coffee to the basic cup of plain coffee. Even the basic cup of coffee is still very complex, holding over 1500 chemicals! The most familiar is caffeine, of course. It takes caffeine about 30 minutes to be fully absorbed by our bodies. Once in the bloodstream, it actually does enhance thought process and the body's capacity for physical activity.

Also, coffee contains antioxidants. Actually, Americans get more antioxidants from coffee than any other food or beverage!

Several studies have suggested that coffee may even reduce the risk of various diseases such as type 2 diabetes, Parkinson's, and Alzheimer's!

Question Your World - How often does it thunder??

Thunder!! by ScienceMuseumofVA

How often does thunder happen on Earth?

A LOT!! 2,000 times per minute!! Also impressive is the amount of lightning that strikes the Earth every minute. 6,000 lightning strikes per minute! These bright flashes and loud rumbles of thunder are scary to some, but rain fall is a vital part of what makes Earth such a wonderful place for us to live on.

Here's an idea. Instead of being startled by the next thunder rumble you hear, you can use it to do a mini weather forecast.
Once you see lightning, just count the amount of seconds before you hear thunder. Then divide that number by 5.

Example:
(seconds between the lightning flash and hearing thunder) 10/ 5 = 2
The storm is 2 miles away from you!
That's enough time to grab an umbrella!

Thunder is pretty impressive stuff.

Question Your World - Breathing

Question Your World - Breathing by ScienceMuseumofVA

Our bodies are pretty amazing and complex! A lot of the involuntary actions that we do every single second keep us alive and healthy. Breathing, for example, is one of the most basic functions of the human body. So, how often does a person do this? Well, on average about 15 times a minute! This varies based on activity level, but on average we are clocking in at around 15 breaths per minute. Check it out, do an experiment, try to count how many times you inhale/exhale in a minute. Try it while laying down, sitting up, walking, maybe even running.

Question Your World - Megacities!! Happy New Year!!

Question Your World - Megacities! by ScienceMuseumofVA



In 1950 there was only one city on the planet that held 10 million (plus) people. Now there are several more. As the population of our planet grows, as do the amount of megacities. Tokyo is high a top the list with almost 34 MILLION people!! Talk about a MEGA-city! These cities also happen to be some of the most watched places for New Years fun! So, this year when you're watching the ball drop, be sure to consider the amazing amount of people that are in New York, Paris, Tokyo, Delhi, and various other megacities all around the world! Happy New Year everyone!!

Question Your World - Bad Predictions...about computers

Question Your World - Bad Predictions by ScienceMuseumofVA

So, things have changed a lot since 1943. Back then the computer industry was tiny compared to the giant booming, seemingly endless industry that it is these days. Thomas Watson has been quoted (or misquoted depending on who you ask) about how the world market could hold maybe 5 computers. Five computers?? Really?? Well, currently there are nearly 1 billion personal computers on the planet right now! If these trends continue we should hit the 2 billion mark in the year 2015. Wow! Motherload of motherboards! Wait, it gets better. This calculation is only based on personal computers. Once you factor in the machines used by various companies (big and small) and the millions used by governments around the world, that number becomes significantly larger!

Regardless, that quote sure was a sign of the times. Those words could never be said today.

Question Your World: Thanksgiving Priceless Science

Happy Thanksgiving everyone!

One of the most common misconceptions about this tasty holiday is based around some simple chemistry. The amino acid in question is Tryptophan! The most popular source of this culinary chemical on your dinner table is turkey, however there is a little myth that we need to clear up. Though turkey does contain tryptophan, you should know that turkey is actually not the most tryptophan filled food. In fact its not even close. There are several other foods that contain way more of this chemical than your Thanksgiving centerpiece.

For example eggs, soybeans, pumpkin seeds, milk, and sesame seeds all have way more tryptophan than the turkey on your plate! If you want to see a chart of tryptophan break down, follow this handy dandy Wikipedia link: http://en.wikipedia.org/wiki/Tryptophan

So, why do we get tired if its not this chemical agent? Well, the answer is actually the same as why you get tired after running a few miles, work. Your body is just working overtime to digest the vast amounts of food you are eating on Thanksgiving. So, this year when the post-dinner zzz’s find you, just know that your body is tired from digesting the mashed potatoes, cranberry sauce, rolls, green beans, pumpkin pie, and…oh yeah…the turkey.

Have a tryped out Thanksgiving everyone!

QUESTION YOUR WORLD: So, exactly, how big is a BILLION?

Billion by ScienceMuseumofVA


How big is a billion?

Well, lets count:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, errr...999,999,998...999,999,999..1,000,000,000!! Whew!! Took a bit longer than we thought. A billion is a huge number!! If you were to count from one to a billion you would need nearly 96 years! Keep in mind this is straight counting, no food, bathroom breaks, tv shows, nothing! When news headlines reference billions of dollars or when you hear about the billions of stars in our galaxy, it can be hard to grasp the enormity of the data, so lets put some perspective on this giant number.
For instance:
A billion pennies is 10 million dollars.
A billion miles could get from Earth to well beyond Saturn
Or a billion miles is about 41,000 trips around the Earth.
And a billion seconds is 31 years, 8 months, and 12 days...That’s enough time for you to do about a billion things!

**side note**...check out this cool link on the time it would take to collect a billion dollars, http://www.classroomtools.com/billion.htm. Yikes!





Also, on April 9, 2012 Facebook bought Instagram for $1 Billion dollars...that's a lot of money!!

QUESTION YOUR WORLD: What's auto racing ever done for my life?

Racecar Inventions by ScienceMuseumofVA

In the early days of auto racing a second person was used as a spotter to look for other vehicles and check the gauges. All that changed when Ray Houron won the inaugural Indy 500 in great part to his stunning new invention, the rear view mirror. This eleminated the weight of the extra person and began a tradition that is still used to this day.

Also, in 1922 Barney Oldfield installed a major safety device in his car, the seat belt. About a quarter century later the factories in Detroit took notice and started to instal them their vehicles.

Fuel additives, tire technology, disc brakes? Yep, you guessed it! All invented to make race cars run smoother and safer. Thanks to these speed hungry technichians many of these inventions can be found in your driveway!!

Drive safely everyone!

QUESTION YOUR WORLD: How many people live on Earth?

Population 7 Billion! - Question Your World by ScienceMuseumofVA

There's a pretty good chance that you've seen some other people today somewhere. Well, we are currently ushering in a new milestone for humanity, 7 billion people. That's right, the Earth is home to 7 billion of us. This is most impressive considering that it took us nearly 199,000 years to get from very few of us to 1 billion of us. 1804 marked the year when humanity reached the billions. The thought of 1 billion people in 1804 is pretty interesting, but pails in comparison to the exponential growth that our population saw soon after. Check out how we grew from 1 billion to 7 billion:
1804 - After nearly 200,000 years we reached 1 billion
1930 - 2 billion
1960 - 3 billion!
1974 - 4 Billion!!
1987 - 5 BILLION!!!
1999 - 6 BILLION!!!!!!
2011 - 7 BILLION!!!!!!!!!!

So nearly 199,000 years to get to 1 billion and only 207 years to get to 7 billion! That's some exceptional exponential growth!

QUESTION YOUR WORLD: Happy Halloween - priceless science

Hello boys and ghouls! Once again, the equinox has happened and daylight savings time has not ended yet, which means its time for Halloween!! Check out the video clip for some fun with Halloween numbers!

That's right $2 BILLION spent on candy each year for Halloween. What a sweet research project this was! For more information check out this link from the National Retail Federation, . They've studied up and surveyed a lot of information about what flies off the shelf around Halloween.

Also, all that candy means a lot of sugar in a lot of mouths! That's the tooth folks! Our teeth are pretty amazing actually. Check out some interesting facts on teeth for all of you that want to bite into this topic a bit more:

http://www.infobarrel.com/15_Facts_about_Teeth#axzz1bFadL861


http://library.thinkquest.org/J0112820/facts.html

Whoa! Sharks have about 40 sets of teeth in their lifetime? A Chinese dentist once built a tower out of 28,000 human teeth??
Chew on that for a while!

Lastly, be sure to spot an awesome science based costume this year!! They can be as simple as a scientist or as complex as an atom! .

Be safe and have fun out there! Happy Halloween from us here at the Science Museum of Virginia!

Their Final 4th of July...

On July 4, 1826, our nation celebrated its 50th birthday. Two old patriots, former arch rivals and now close friends, began the day but did not finish it. Thomas Jefferson and John Adams died on the same day in their own homes hundreds of miles apart on the 50th anniversary of their signing the Declaration of Independence. What could explain this strange occurrence?


1. Coincidence – well, it could be a coincidence, but what a significant one! They died on the same day, a momentous date and historic anniversary, especially for them. Both had lived much longer than the average male of the time (Adams was 90); Jefferson’s health had been failing for some time. It would be an incredible coincidence; the odds are mind-boggling.

2. Conspiracy – did someone else cause their deaths? In that time, it was unlikely due to communication problems over long distances, but it could have happened...

3. Divine intervention – well, that is possible…

4. Waiting for the day – do you suppose each of them wanted to see the nation turn 50 and willed themselves to live until that day? Perhaps…

The last words John Adams uttered were “Thomas Jefferson survives,” but Jefferson had passed away a few hours earlier.

What do you think?

Scheila Sports a Plume

Meet Scheila and her friends:

http://www.nasa.gov/topics/universe/features/asteroid-collision.html

An asteroid named Scheila lives in the asteroid belt between Mars and Jupiter with millions of other asteroids.  Scheila is about 70 miles across and completes her orbit around the sun every five years.  Late last year, astronomers noticed Scheila had gotten noticeably brighter and was adorned with plumes.  After studying data from the Hubble Space Telescope and Swift satellite, they determined Scheila had collided with one of her fellow asteroids at 11,000 miles per hour (ouch!).  The plumes made Scheila appear comet-like and were most likely small particles of dust from Scheila’s surface.  In two months, the dust had dissipated and Scheila was back to normal.  Thanks to Hubble and Swift, astronomers could study the collision before all evidence of it disappeared, allowing them a peek inside an asteroid.  Now I wonder what Scheila thought of that…

Celebrate Earth Day

This Earth Day, I could pass along “green” tips on how to save energy and reduce your carbon footprint, but I will save that for another time. Instead, let me make a suggestion: go OUTSIDE this weekend! Take your dog for a walk, plant a vegetable garden, play outdoor games with your children, visit a local park, take a hike and look for wildlife, or just sit in the sun and appreciate its warmth (with appropriate sunscreen, of course).


If you are a bit more ambitious, visit an Earth Day Festival near you – the Richmond Earth Day Festival will be held Saturday, April 23 in the New Manchester District on the south end of the 14th Street Bridge. Streets will be blocked off and filled with artists, vendors, farmers and fun activities for all ages.

You could also visit the Science Museum of Virginia and explore the energy exhibits, such as New Energy Virginia, Watt Wall, Virginia Tech Solar House and others. When you are ready to get off your feet, enjoy a breathtaking film in the IMAX Dome. And don’t forget the popcorn!

Happy Earth Day, y’all!

The Aluminaut & a 1960s View of the Future

In the collection of the Science Museum of Virginia is the world's first all aluminum submarine: the Aluminaut. The Aluminaut was built by Reynolds Metals Co. in 1964 and donated to the Science Museum of Virginia in 1995.

The above drawing is a futuristic view of the world as envisioned by Reynolds Metals Co. in the mid-1960s for what the future would hold for the Aluminaut (shown as the dark vessel at top left). Here are some projects it was believed the Aluminaut would initiate:

• Producing electricity through subsurface dams set up over strong ocean currents


• The ability to move large amounts of people safely underwater as opposed to dangerous travel above the surface during hostile weather or attacks


• Vacationing in the ocean in underwater cities


• Modifying the weather and stopping hurricanes by constructing underwater baffles to deflect cooler water upward


• Constructing oil refineries where workers could live and work underwater (as depicted in the above drawing)

Come visit and see the submarine for yourself- the Aluminaut is currently on display at the Science Museum of Virginia.

What one degree will do...

If you lowered the thermostat on your water heater by one degree this year, you could save enough energy to microwave 207 bags of popcorn or power a fish tank for 19 days.

If 1000 people joined you, we could power 10 homes for 30 days or power a hospital for 4 days.

What one light bulb can do...

If you replaced one incandescent light bulb with a CFL, you would save enough energy to watch TV for 429 hours, watch 215 DVDs or play a video game for 201 hours.

If 1000 people joined you, you could power a roller coaster for 34 days, power a shopping mall for 31 days or power Alaska for 8 hours.
