Happy Fibonacci Day!

In addition to this Thursday being Thanksgiving here in the States, November 23 is also Fibonacci Day! If you remember from math class, the Fibonacci sequence is an integer sequence in which every number after the first two is the sum of the two preceding numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...
While it may look simplistic, the sequence actually has far reaching implications, more than even Fibonacci himself probably imagined!

  • Named after Italian mathematician Leonardo of Pisa, known as Fibonacci, who introduced the sequence to Western European mathematics in the 1200's.
  • Used in many different mathematics applications & algorithms, but also in investments, artwork, even architecture!*
  • The sequence can even be found in nature! Fibonacci spirals, aka 'nature's numbers' can be seen on flower petals and seeds, plant leaves, nautilus shells, the DNA molecule, and even hurricanes and galaxies.
  • The spiral is charted as a series of connected quarter-circles drawn inside an array of squares with Fibonacci numbers for dimensions. (see right).

No matter what order you like your numbers in,
our Indexed Racks keep samples organized!

  • Available in standard or serpentine numbering
  • Ideal when cell identification/location is critical
  • Round holes with tight tolerances hold tubes firmly

 

*There is so much more to explore in the Fibonacci sequence! We highly encourage you to do some research on your own to truly appreciate how complex and interesting this sequence is.

In observance of the Thanksgiving holiday, SP Scienceware will be closed Thursday, November 23 and Friday, November 24.

Tipping the Scales

Tipping the Scales

When does a pumpkin go from big to giant? 100 lbs? 1000 lbs? More? In the 1980's, the heaviest pumpkin weighed in at just over 400 lbs. Now, pumpkin growers are aiming for 2000+ lbs, and getting heavier every year! Here are some interesting facts about these scale-tipping giants!

  • Virtually all giant pumpkins are descended from "Dill's Atlantic Giant" variety which took 30 years to cultivate.
  • High-pedigree hybrid seeds of prize-winning giant pumpkins can cost growers anywhere from $10-100 or more per seed.
  • The world record for the heaviest pumpkin is held by Mathias Willemijns of Belgium. The pumpkin weighed 1,190.49 kg (2,624.6 lb)
  • Bragging rights are not all you win for growing a giant: the recent winner of the 2017 Half Moon Bay Champion Pumpkin Weigh-Off in California took home $7 per pound for his 2,363 lb pumpkin (that's $16,541!)

When weighing powders and not pumpkins (or other solid matters), SP Scienceware has a variety of sampling tools that double as weigh boats!

The Giant Toppling Tower

Tournament of Champions!

Four Days…Four Teams…WHO WILL COMPETE?

At SP Scienceware, we're always looking for ways to encourage teamwork within our company. But we also like to have a little fun! What better way to do both then have a lunchtime Giant Toppling Tower Tournament!

Eight 2-person teams competed for a chance at the Championship. Some never played before, some were self-proclaimed "masters".

The competition was fierce. Hearts raced. Hands shook. Over 4 days, the competition whittled down to 4 teams who would compete in the championship...

How to Choose a Desiccator


Things that are usually better kept dry: 

Bread, Crackers, Potato Chips (basically all the starchy carbs), Cosmetics, Cell Phones, Vinyl Records, Photographs, Tax Returns, Powder Chemicals...

And so we bring you: 

1. What Size Desiccator Do I Need?

2. What Shape Do I Need - Round or Cabinet Style?

3. Which Method of Desiccation is Right for My Application?

For an in-depth guide to these questions and more,

See the All About Dessicators Guide!

Sneak Peak: Methods of Desiccation

Method
Pros
Cons
Standard
Economical; flexible; portable Requires monitoring
Automatic
Desiccant is continuously regenerated; minimal monitoring; precise control Generally more expensive than standard desiccators
Gas Purge
Achieve desired humidity level faster; dust free; creates an ultra dry environment Requires access to inert gas (such as argon or nitrogen)
Vacuum
Best for total dry storage; can also be used for degassing techniques Requires access to vacuum pump; how long vacuum is maintained can vary from models

Now that you know how to choose a desiccator, check out the different models available from Bel-Art - SP Scienceware:

Funnels + Cake

Image: Funnels + Cake = A Tasty Treat

It's fair and carnival season here in the US which means plenty of fried foods, including funnel cake - a round pile of crispy fried dough usually covered in powdered sugar. But where did funnel cakes actually come from? And, would you believe this deep fried dough is actually considered a 'lower calorie treat'?!

      • The name 'funnel cake' comes from the way batter is poured through a funnel into hot oil.
      • These fried fritters date back to medieval times, but their modern U.S. origins are commonly associated with the Pennsylvania Dutch, who served funnel cakes to the masses at the Kutztown Folk Festival every year.
    • Similar delights (yep, we're fans!) can be found the world over including:
      • Spain - Churros
      • Canada - Beaver-tails
      • Brazil - Bolinho de chuvas
      • France - Bugnes
      • Portugal - Fartura
      • Germany - Strauben/Strieble
      • Lithuania - Skruzdėlynas

But low calorie?! No way!

Yes way! An average 6-inch funnel cake contains less than 300 calories! The steam produced by the high water content in the batter allows it to puff up, resulting in the light and airy texture. Pile on the toppings like powdered sugar, chocolate, or jelly and it's another story...

Want to make your own funnel cakes at home*, or need funnels for the laboratory?
