Most of the historical data is hidden away in PDFs of these monthly reports, so I had the pleasure of scraping data from scans of dozens of CDC reports that were published 30 years before I was even born. To provide a more visual view of the data set, I charted the per capita marriage and divorce rates below, with a few annotations to denote major historical events. Similarly, after the conclusion of WWI and WWII , those same young men and women coming back from the war seemed eager to elope and start a new life after spending years experiencing the destructive nature of war. Interestingly, the only notable spike in divorce rates in the past years also followed the conclusion of WWII, likely due to many of the pre-WWII marriages coming to an abrupt end once the romance of wartime marriage wore off. It seems when Americans fall on hard times, marriage is one of the first things to take the back seat. One particularly confusing aspect of this data set was the fact that the post-war era in the s and s seemed to experience a significant drop in marriage rates, despite the fact that the s and s were known as a time of nearly-universal marriage in the U. To provide a clearer view of the s and s, I plotted the raw counts for marriages and divorces below. Click here for the interactive version of the raw counts chart With the raw counts in hand, the explanation for the drop in per capita marriage rates becomes abundantly clear:

The first car slows to a stop and picks me up. When I let on to my destination she immediately questions my light load. I could spend hours running through the park chasing clouds, catching frogs and stomping though puddles.

Corneliszoon was granted a patent for his crankshaft in Modern Europe[ edit ] From the 16th century onwards, evidence of cranks and connecting rods integrated into machine design becomes abundant in the technological treatises of the period: Reciprocating piston engines use cranks to convert the linear piston motion into rotational motion. Internal combustion engines of early 20th century automobiles were usually started with hand cranks, before electric starters came into general use.

History Galton whistle, one of the first devices to produce ultrasound Acoustics , the science of sound , starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was discovered by Lazzaro Spallanzani in , when he demonstrated that bats hunted and navigated by inaudible sound and not vision. Francis Galton in invented the Galton whistle , an adjustable whistle which produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans.
The first technological application of ultrasound was an attempt to detect submarines by Paul Langevin in The piezoelectric effect , discovered by Jacques and Pierre Curie in , was useful in transducers to generate and detect ultrasonic waves in air and water. The Mosquito is an electronic device that uses a high pitched frequency to deter loitering by young people.
Animals Bats use ultrasounds to navigate in the darkness. A dog whistle , a whistle which emits sound in the ultrasonic range, used to train dogs and other animals Bats use a variety of ultrasonic ranging echolocation techniques to detect their prey. This includes many groups of moths , beetles , praying mantids and lacewings.
Upon hearing a bat, some insects will make evasive manoeuvres to escape being caught. For many processes in the medical, pharmaceutical, military and general industries this is an advantage over inline sensors that may contaminate the liquids inside a vessel or tube or that may be clogged by the product.
Both continuous wave and pulsed systems are used. The principle behind a pulsed-ultrasonic technology is that the transmit signal consists of short bursts of ultrasonic energy.

You can determine how old your residential water heater is by looking at and decoding data on the water heater’s label. First, locate the manufacturers label with the serial number on the side of your unit.
Purchasing an older home with an existing furnace can be a worry; a furnace often needs replacing after 15 to 20 years, so knowing its age is helpful in determining if a new furnace should be in the budget. Newer units may have a manufacturer’s date listed somewhere on the furnace; older furnaces require a bit more digging by looking at the serial number, which tells the manufacturer various pieces of information, including the age.
Finding the serial number, however, may also require a bit of sleuth work. Look at the interior of the metal door for a label or tag listing the furnace’s serial number. This may also show an actual manufacturer’s date, depending on the company that made the furnace. Older furnaces sometimes had the serial number stamped onto the fan itself, giving the necessary information even when a manufacturing label is absent.

How Old is that Water Heater? Though a water heater is relatively inexpensive compared to the price of a house, repairs for the damage caused when one suddenly has a catastrophic failure is likely to be expensive. This is the reason many inspectors want to be able to give their clients some idea of how old the device is and when they need to begin considering replacement. Your clients need to know the answers to these questions and others.
In other words, there is no set maximum expected service life. In fact, two neighbors with exactly the same brand water heater installed on exactly the same day on the same street in identical houses can have completely different experiences. In some parts of the country it is normal to expect between 10 and 15 years, while in others a homeowner is lucky if the water heater lasts 10 years. The manufacturing date is coded into the serial number of water heaters and, since there are more than different brands of water heaters in this country, trying to memorize every single serial number code at first seems impossible.
