From hurricanes to ancient architecture to the center of sunflowers, examples of the Golden Ratio are all around us.

The Golden Ratio.

Live Science defines the Golden Ratio (also called the Golden Mean or Divine Proportion) as “a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi, after the 21st letter of the Greek alphabet.” As with pi, the golden ratio is a number whose decimal points go on ad infinitum. 1.61803398875… is just the beginning. Phi is usually rounded off to 1.618. The equation is expressed as a/b = (a+b)/a = 1.618…

Phi.

The Golden Ratio has been discovered and rediscovered by mathematicians throughout ancient history and across cultures. The ratio may be seen in the proportions of great ancient architecture including the Great Pyramid of Giza and the Parthenon. Plato (428 - 347 BCE) described the ratio as the most “universally binding mathematical equation.”

The Golden Ratio is closely related to the Fibonacci Sequence discovered by Leonardo Fibonacci in 1202. Fibonacci Sequence is a sequence of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34… The expression is written as xn = xn-1 + xn-2. The Ratio of two successive Fibonacci numbers roughly equal the Golden Ratio--especially as the numbers increase in size. 

The Golden Ratio also informs the Golden Rectangle, which is considered the most visually satisfying geometric from. The ratio of the length and width of the Golden Rectangle equal the Golden Ratio. The Golden Rectangle is often employed in photography, art, and design (but more on that in a later post).

Outside of the realm of mathematics, the Golden Ratio plays a surprisingly significant role in the natural world. In nature, the Golden Ratio can be found in the arrangement of flower petals in some flowers, seed heads, pinecones, tree branches, shells, spiral galaxies, dolphins, starfish, sand dollars, honey bees, hurricanes, human fingers, and even our DNA molecules.

Moreover, the Golden Ratio, loosely speaking, can be found on the faces of individuals that are generally found most attractive. A geometric “beauty mask” can help predict whether or not the proportions of an individual's face will be deemed attractive by the average person. Of course, we know that beauty comes down to more than a math equation and it's important to promote concepts of beauty that move past traditional definitions--but it's interesting to think about the way this one equation plays such an important but quiet role in our perception of aesthetics.

Should You Store Your Jewelry in a Safe-Deposit Box?

Posted on June 30, 2016 by Mary Hood | 0 Comments

For those rarely-worn heirloom jewels, a safe-deposit box at the bank is likely your safest, most practical storage option. This article discusses important things to consider before finalizing your jewelry storage plan.

Safe-Deposit Box Basics

A safe-deposit box is a mini safe-like box secured inside a bank. Most banks and credit unions offer safe-deposit boxes for rent.  Because you will only have access to the box during the bank’s business hours, safe-deposit boxes are best for items that you won’t need in a moments’ notice or in an emergency. When setting up a safe-deposit box, consider who you’d like to be able to access the box in case you are unable to. Trusted individuals may include heirs, a spouse, or a designated power of attorney.

Unlike the money you store in the bank, the valuables in your safe-deposit box are not insured by the government or the banking institution. Therefore, it may be wise to purchase separate insurance from a company that specializes in policies for safe-deposit box contents or consult with your home insurance agent to add a rider or personal article floater for specific valuable items stored in the safe-deposit box to your home insurance policy. 

Finally, make sure you inventory your safe-deposit box and keep a current list of its contents.

 There is no guarantee that your valuables will be perfectly safe in a safe-deposit box—which is why insuring those valuables is a smart plan. Although disasters are rare, they can happen. After the terrorist attacks on September 11, 2001, roughly 1,300 safe-deposit boxes were collateral damage.

That being said, safe-deposit boxes are typically your safest bet since they are protected from home disasters (flooding, fires, and burglaries), which are more likely to occur than bank disasters.

What about a Home Safe?

Although a home safe is certainly more secure than an unlocked jewelry box—and less expensive than a bank safe-deposit box, most home safes have significant vulnerabilities. Many home safes are less than 100 pounds, so it’s not impossible for someone to walk away with one. They also tend to be easier to crack than bank safe-deposit boxes. The average non-fireproof home safe will only hold up for about an hour in a fire, so if you do rely on a home safe for some of your valuables, it’s wise to invest in a fireproof safe.

The Cost of Using a Safe-Deposit Box

The cost of a box varies depending on its size. Some banks may also offer existing customers discounts on safe-deposit boxes. The following estimates are sourced from Financial Web:

  • The smallest safe-deposit box available is 2"x5" and 12” long. Annual rent is typically between $15 and $25 a year.
  • A medium safe-deposit box measures 4"x10" and is 12” long. Annual rent is typically between $40 and $65.
  • The largest safe-deposit box offered is 15"x22" and 12” long.  Annual rent is typically between $185 and $500.

Key deposits are usually $10 to $25 per month, and a replacement key is usually $20.
