Whisky

Whisky is a spirit distilled from malted grain, barley or rye. The word whisky is originated from the Old English word usquebae. The word is derived from the words uisce, which means water, and bethu, which translates to life. Summing it up, the word whisky basically means 'water of life'.

Vanilla vs. French Vanilla Ice Cream

Both are made with vanilla beans for flavor. Vanilla ice cream is more white and French vanilla ice cream tends to have a slightly yellow coloring.

The name French vanilla is derived from the classic French way of making ice cream using an egg custard base. French vanilla ice cream has egg yolks, which give it a smoother consistency and its distinctive yellow hue. The taste is a bit richer and a bit more complex than a regular vanilla, which is made with just milk and cream.

Happy Friday

A perfect smile reflects perfect happiness. Happiness reflects the sunshine of a perfect smile.

I always try to smile and reflect happiness, especially on a Happy Friday!

Medicare Birthday

On July 30, 1965, at a public ceremony in Independence, MO., President Lyndon Baines Johnson signed Medicare into law. Moments later, the 36th president of the United States presented America's 33rd president, Harry S. Truman, then 81 years old — the nation's first Medicare card.
Medicare provides health insurance to Americans age 65 and older and to younger people with certain disabilities or health conditions. At its creation, Medicare consisted of two parts: Medicare Part A hospital insurance coverage and Medicare Part B, an optional medical insurance program.

Medicare's first beneficiaries paid a $40 annual deductible for Part A. The monthly premium for Part B was $3.

CT, MRI, PET and SPECT Scans

Had a chance to sample some of this technology recently and realized many folks are not aware of what the terms actually mean. Each requires a distinct type of radiology equipment used to perform mostly medical procedures. Each piece of equipment costs millions of dollars and data shows that more machines cause more tests to be performed. Various pieces of equipment may look different than the pictures below, due to company design and age of the equipment.

A CT (computed axial tomography) scan uses X-rays, an MRI (Magnetic resonance imaging) scan uses magnetic and radio waves, a PET (Positron emission tomography) scan uses a radioactive substance injected in the body and gamma rays, and SPECT (Single photon emission computed tomography) scan uses a radioactive substance injected into the body and a gamma camera. Tomography is a technique for displaying a representation of a cross section through a human body or other solid object using a penetrating wave.

CT Scanner

A CT scan is better suited to cancer, pneumonia, abnormal chest x-rays, and bleeding in the brain, especially after an injury. A CT scan shows organ tear and organ injury more quickly, so is more suitable for trauma cases. Broken bones and vertebrae are more clearly visible on a CT scan. CT scans provide a better image of the lungs and organs in the chest cavity between the lungs.

MRI Scanner

An MRI is better for examining the spinal cord. An MRI show a more visible brain tumor.

A CT scan does not show tendons and ligaments, but an MRI does.

A CT or MRI scan can assess the size and shape of body organs and tissue, but they cannot assess how these work.

PET Scanner

The PET system detects pairs of rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body. Three-dimensional images of tracer concentration within the body are then constructed by computer analysis. A PET scan can show how an organ works, and is often used with a CT or MRI scan. PET scans are used to diagnose a condition or to track how it is developing. PET scans are used to investigate epilepsy, Alzheimer's disease, cancer, and heart disease.

The SPECT system works like a PET, but uses gamma rays to show a tracer dose of radioactive material injected into the body. The material moves to areas of bone and elsewhere highlighting healing or cancer progression as it is usually lit up on SPECT scans.

Chicken Facts

Here is something to cluck about. The UN's Food and Agriculture Organization concluded that, as of 2014, the world has about 21 billion chickens, which produce the 79 billion eggs eaten by Americans every year. As the human population grew by 80 percent between 1970 and 2008, the global chicken population grew by 262 percent. That makes three chickens for every human on earth.

Al Capone

A famous crime boss during prohibition in the US was jailed for income tax evasion. He was released from Alcatraz prison on November 16, 1939 and died January 25, 1947 with few of his friends attending his modest funeral.

He died penniless after once earning $40 million a year. He struggled to support his family on an income of $600 a week, which was provided by former associates of the Chicago Outfit. After his death, his wife, Mae, whom he married in 1918, was forced to sell their home due to financial constraints. She died during 1986.

Wordology, Lidar

The word is an acronym for Light Detection and Ranging. The US military and NASA invented the Lidar technology during the early 1960s for measuring distance in space. Its first commercial usage did not occur until 1995.

It uses ultraviolet, visible, or near infrared light from lasers. Radar (Radio Detection and Ranging) uses radio or electromagnetic waves. Lidar used in cars is low powered and classed as 'eye-safe' allowing it to be used with few safety precautions.

Some refer to Lidar as laser radar, however it is not. It is more precise than radar, because the speed of light is a constant, so a laser can make extremely precise measurements of distance by computing the time between when the device emits a laser pulse and when it detects the reflection. Sound travels about 1,000 feet (300 meters) per second and light travels about 984,000,000 feet per second (300,000,000 meters). Also, radar wavelengths suffer from atmospheric conditions, such as humidity, fog, rain, snow, and temperature, but do perform better in smokey or dusty conditions.

A laser unit fires a short pulse of light. The pulse rebounds off a point, such as the rear of the car in front and is detected by a sensor in the laser unit. A computer connected to the unit measures the time between the initial pulse and the light return and, using the speed of light, calculates the distance the light has traveled. It creates a high-resolution 3D map of the surrounding environment. The best sensors can see details of a few centimeters at distances of more than 330 feet or 100 meters.

Currently most autonomous cars use some combination of Lidar, Radar, and camera. Lidar is precise, Radar is good at motion, and cameras are good for depiction. Each technology has strengths and weaknesses, so automakers and others are trying to find the best combination of strengths at the lowest cost.

Father and Son

John Scott Harrison was a member of the United States House of Representatives from Ohio and the only person to be both the child and the parent of US Presidents. He was also the grandson of Declaration of Independence signer, Benjamin Harrison V. He was the father of thirteen children.

His father, William Henry Harrison was the ninth President in 1841 and his son, Benjamin Harrison, was the 23rd President from 1889 to 1893. Harrison did not live to see his son become President.
