Alright, let’s break down simple interest, a fundamental concept in math that’s quite handy in understanding how money grows over time.

Imagine you have some money, let’s call it the principal. The principal is like the seed money you start with when you plant a financial seed. Now, when you put that money into a savings account or lend it to someone, you usually expect to get a little extra back over time, right? That extra bit is the interest.

Here’s where the three amigos come in: principal, rate, and time. The principal is the amount of money you start with. The rate is how much interest you earn on that money as a percentage. And time is, well, time – how long your money stays in the account or is lent out for.

So, how do we calculate simple interest? It’s as easy as pie! Literally, it’s Principal × Rate × Time (expressed as a fraction of a year). Here’s the formula:

Simple Interest = Principal × Rate × Time

Let’s say you have $100 (that’s your principal), and you’re getting an annual interest rate of 5%. If you leave that money for one year, the simple interest would be:

Simple Interest = $100 × 5% × 1 = $5

That means you’d earn $5 in interest for leaving your $100 untouched for a year. But let’s say you leave it for two years:

Simple Interest = $100 × 5% × 2 = $10

See how it doubled? That’s because time is a multiplier here. The longer you leave your money, the more interest you earn.

And voila! You’ve just unlocked the secret to calculating simple interest. It’s a neat little tool that helps you understand how your money can grow over time, simply by sitting in an account or being lent out.

Samhain and Halloween

by Christopher Rudolph

The Celtic Festival of Samhain, which originated over 2,000 years ago, has significantly influenced the modern celebration of Halloween in the United States. Celebrated at the end of October and the beginning of November, Samhain marked the end of the harvest season and the beginning of winter, a time the Celts associated with the boundary between the living and the dead becoming blurred. On the night of Samhain, the Celts believed that spirits of the dead returned to earth, leading to rituals that honored both the deceased and nature’s cycles. These ancient practices laid the foundation for Halloween as we know it today.

One of the most significant connections between Samhain and modern Halloween is the belief in spirits and supernatural beings roaming the earth. During Samhain, the Celts would light bonfires and wear costumes, often made of animal skins, to ward off harmful spirits. This tradition evolved into today’s practice of dressing up in costumes for Halloween. While modern costumes are more about fun and entertainment, the custom of wearing disguises to protect oneself from spirits can be traced back to Samhain.

Samhain also involved the practice of leaving offerings of food and drink to appease wandering spirits. This has similarities to today’s Halloween tradition of trick-or-treating. Although now centered on children receiving candy, the idea of offering food to spirits evolved into a festive activity that still retains a sense of supernatural fun.

Furthermore, the lighting of bonfires during Samhain to guide spirits and protect the living is echoed in Halloween’s association with fire and light, especially through the use of Jack-o’-lanterns. The carved pumpkins, often featuring spooky faces, are a modern version of the protective lanterns once made from turnips or gourds.

Samhain’s ancient customs have influenced many aspects of modern Halloween celebrations in the U.S., from the focus on costumes, spirits, and communal gatherings to practices such as trick-or-treating and the use of light to ward off the darkness.

Samhain is pronounced sah-win (phonetic standard) ; ˈsɑ wɪn (IPA)
