Spencer Alexander McDaniel:

Well, first, let us talk about where the name "Jesus Christ" comes from. The name Jesus is an Anglicized form of the Latin name Iesus, which is in turn a Latinized form of the ancient Greek name Ἰησοῦς (Iēsoũs), which is, in turn, a Hellenized form of Jesus's original name in ancient Palestinian Aramaic, which was יֵשׁוּעַ (yēšūă‘), a shortened form of the earlier Hebrew name יְהוֹשֻׁעַ (y'hoshuaʿ), which means "Yahweh is Salvation."

y'hoshuaʿ is the original Hebrew name of the hero Joshua, the central figure in the Book of Joshua in the Old Testament. Consequently, yēšūă‘ was one of the most common male given names in Judaea and Galilee during the early part of the first century CE when Jesus was alive. There are even multiple other people with the exact same name mentioned in the New Testament, including Jesus Barabbas in the Gospel of Mark and Jesus Justus, an apostle mentioned in the Book of Acts and in the Pauline Epistles.

Although people today often treat the word Christ as though it is Jesus's last name, it is actually not a name at all, but rather an epithet (i.e. a descriptive title). The English word Christ is an Anglicized form of the Latin word Christus, which is, in turn, a Latinized form of the ancient Greek word Χριστός (Christós), meaning "anointed one." The word Χριστός is used in the New Testament as a Greek translation of the Hebrew title מָשִׁיחַ (māšîaḥ), which has roughly the same meaning.

In antiquity, the title of māšîaḥ was not exclusively specific to any one particular person; instead, it was a generic title that could be applied to anyone who was regarded as fulfilling the role of God's anointed. For instance, in Isaiah 45:1, the title is applied to Cyrus the Great, the shah-in-shah of the Achaemenid Empire, who freed the Jews from captivity in Babylon after he captured the city in 539 BCE and allowed them to return home to rebuild their Temple in Jerusalem.

Now that we have that covered, we can proceed to explain where the phrase "Jesus H. Christ" most likely comes from. Most Christians are familiar with the Chi Rho monogram. If you are not familiar with it, here it is:

It is composed of the capital forms of the Greek letters chi ⟨Χ⟩ and rho ⟨Ρ⟩, the first two letters of the Greek word Χριστός, superimposed over each other. It is a sort of clever abbreviation that was used by early Christians to signify "Jesus" without having to write out his full name.

There is, however, another monogram used to represent Jesus that many people are less familiar with: the IHϹ monogram. Here is one form of it:

While the Chi Rho monogram is composed of the capital forms of the first two letters of the Greek word Χριστός, the IHϹ monogram is composed of the first three letters of Ἰησοῦς, which, if you recall, is the Greek spelling of the name Jesus.

The first letter is the Greek letter iota ⟨I ι⟩, which looks like the Latin letter ⟨I⟩ and makes the [i] sound as in the word machine, or sometimes the consonantal [j] sound as in the word yellow. The second letter is the Greek letter eta, which makes the long E sound, but which looks like the Latin letter H ⟨H η⟩. The third and final letter is the lunate sigma ⟨Ϲ ϲ⟩, a form of the Greek letter sigma which looks extremely similar to the Latin letter ⟨C⟩ and makes the [s] sound as in the word soft.

These are the first three letters of the name Ἰησοῦς, the Greek spelling of the name Jesus used in the original Greek text of the New Testament. At some point, however, presumably sometime in the early 19th century, ignorant Americans who were accustomed to the Latin alphabet and who knew nothing of the Greek alphabet mistook the letters of the IHϹ monogram for the Latin letters J, H, and C. They concluded that the J must stand for "Jesus" and the C must stand for "Christ," but then no one could figure out what the H stood for. Apparently, some people just concluded, "Hey, I guess H must be his middle initial!"

Eventually, the phrase "Jesus H. Christ" became something of a joke and it began to be used as a mild expletive. In his autobiography, the American author Mark Twain (a.k.a. Samuel Langhorne Clemens; lived 1835–1910) observed that the phrase was already in common use when he was still a young lad. Twain tells a humorous anecdote of how, in around 1847, when he was apprenticed to a printer, the evangelical preacher Alexander Campbell, the leader of the "Restoration Movement," ordered the printer to whom the young Samuel Clemens was apprenticed to print some pamphlets for one of his sermons.

Unfortunately, the printer accidentally dropped a few words and, in order to avoid having to reset three whole pages of text, made space to fill in the missing words by abbreviating the name "Jesus Christ" to simply "J. C." at one point in the text. The pious Reverend Campbell, however, insisted that the printer must not "diminish" the name of the Lord; he insisted that he needed to include the full name, even if it meant resetting three whole pages of already set text. The printer reset the text, but, because he was annoyed by the reverend, instead of changing the text of the pamphlet to say simply "Jesus Christ," he changed it to say "Jesus H. Christ."

It is important to note that Mark Twain's story is not the origin of the phrase, but it is an early piece of evidence of the phrase being used.

How Is a Sunscreen's SPF Calculated?

I’m a pale person. A very pale person. Which means that during these hot summer months, I carry sunscreen with me at all times, and apply it liberally. But I’ve never really understood what those SPF numbers meant, so I asked some sun care to break it down for me—and to tell me how to best apply the stuff so that I can make it through the summer without looking like a lobster.

Soaking up the sun ... safely

SPF stands for Sun Protection Factor, and it indicates a sunscreen’s ability to block UVB rays. The concept was pioneered at the Coppertone Solar Research Center in 1972; in 1978, the FDA published an SPF method based on Coppertone’s system, according to Dr. David Leffell, chief of Dermatologic Surgery and Cutaneous Oncology at Yale.

The numbers themselves stand for the approximate measure of time a person who has applied the sunscreen can stay out in the sun without getting burned. Say you get burned after 20 minutes in the sun without sunscreen; if properly applied (and reapplied), SPF 30 will allow you to stay in the sun 30 times longer without burning than if you were wearing no protection at all. So, theoretically, you should have approximately 600 minutes, or 10 hours, in the sun. But it’s not an exact science because the amount of UV light that reaches us depends on a number of factors, including cloud cover, the time of day, and the reflection of UV rays off the ground, so it’s generally recommended that you reapply sunscreen every two hours (or even sooner).

What gives a sunscreen a higher SPF comes down to the product’s formulation. “It’s possible that an SPF 50 might contain slightly more of one or more sunscreen active ingredients to achieve that higher SPF,” Dr. Patricia Agin, president of Agin Suncare Consulting, says. “But it’s also possible that the SPF 50 might contain an additional active ingredient to help boost the SPF performance to SPF 50.”

No matter what SPF your sunscreen is, you’ll still get a burn if it’s not properly applied. So let’s go over how to do that.

How to apply sunscreen

First, make sure you have a water-resistant, broad spectrum sunscreen—which means that it protects against both UVB and UVA radiation—with an SPF of at least 30. “Typically, you don’t have to buy sunscreen that has an SPF higher than that unless you have very sun sensitive skin,” Leffell says. “That’s a very small percentage of the population.” (Redheads, people with light eyes, and those who turn pink after just a few minutes in the sun—you’ll want to load up on SPF above 30.)

Twenty minutes before you go out to the beach or the pool, begin to apply your sunscreen in an even coat. “Don’t apply it like icing on a cake,” Leffell says. “I see these patients and they’ve got the tops of their ears covered with thick, unevenly applied sunscreen, and that’s not a good sign.” Sunscreen sprays will easily give you that even coat you need.

Whether you’re using lotion or a spray, when it comes time to apply, Leffell recommends starting with your scalp and face, even if you plan on wearing a hat. “Make sure you’ve covered the ears and nose and under the eyes,” Leffell says. “Then, I would move down to the shoulders, and make sure that someone can apply the sunscreen on your back beyond the reach of your hands.”

Other areas that are important that you may forget to cover, but shouldn’t, are the tops of your feet, the backs of your hands, and your chest. “We see it all the time now—the v of the chest in women has become a socially and aesthetically huge issue when they are 50 and beyond. Because even though they can treat their faces with all sorts of cosmetics and procedures, the chest is much harder, and they are stuck with the face of a 40-year-old and the chest of a 60-year-old. You want to avoid that using sunscreen.”

Another important thing to keep in mind: Water-resistant doesn’t mean waterproof. “I always tell patients to reapply every couple of hours while you’re active outdoors," Leffell says, "and always reapply when you come out of the water or if you’ve been sweating a lot, regardless of whether the label says water resistant."

Determining whether or not you’ve succeeded in properly applying your sunscreen is easy: “You know you’re applying your sunscreen properly if, after the first time you’ve used it, you haven’t gotten a burn,” Leffell says.

Agin has a caveat, though: "It’s not a good idea to think of sunscreens only as a way to extend your time in the sun," she says. "One must also understand that even before becoming sunburned, your skin is receiving UV exposure that causes other damage to the skin. At the end of the 600 minutes, you will have accrued enough UV to cause a sunburn—one Minimal Erythema Dose or MED—but there is pre-MED damage done to skin cells’ DNA and to the skin’s supporting structure of collagen and elastin that is not visible and happens even before you sunburn. These types of damage can occur without sunburning. So you can’t measure all the damage done to your skin by only being concerned about sunburn."

What's the Difference Between Ice Cream and Gelato?

'Tis the season for beach reads, tan lines, and ice-cold desserts. You know it's summer when going to the local ice cream or gelato shop becomes part of your daily routine. But, what exactly is the difference between these two frozen treats?

One of the key differences between the two is butterfat. While ice cream's main ingredients include milk, cream, sugar, and egg yolks, the secret to making gelato is to use much less cream and sometimes little to no egg yolk. This leads to a much smaller percentage of butterfat in gelato. The FDA rules say that ice cream cannot contain less than 10 percent milkfat (though it can go as high as 25 percent) while gelato, much like soft serve, stays in the 4- to 9-percent range.

The churning method for both also differs, which affects the treat's density. Ice cream is churned at a much faster pace, leading to more air being whipped into the mixture. Ice cream's higher butterfat content comes into play here—due to all of that milkfat, the mix absorbs the air more readily. Gelato, on the other hand, is churned at a slower pace and absorbs far less air, creating a much denser dessert.

You also might have noticed that the serving style for the two treats aren't the same, either. In order to get those perfectly stacked ice cream scoops on a cone, buckets of ice cream must be stored at around 0°F to maintain its consistency, while the softer gelato is stored at a warmer 10°F to 22°F. Ice cream is then scooped into fairly uniform balls with the round ice cream scooper, whereas a spade or paddle is best for molding gelato into mound in a cup or a cone.

You can't really go wrong with either gelato or ice cream on a sweltering summer day, but there is one more difference to keep in mind while you debate which to get: taste. If you want a bolder flavor, you'll want to go with gelato. Because of the density of the cream and because there's less butterfat to coat your taste buds, gelato can seem to have more intensity to its flavors.
