How Breath Alcohol Analysis Works

Alcohol shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream. Alcohol­ is not digested upon absorption, nor chemically changed in the bloodstream. As blood circulates through the lungs, some of the alcohol moves across the membranes of the lung’s alveoli, into the air stored within the lungs. Because the alcohol concentration in the breath is related to the concentration in the blood, an approximate measurement can be identified when using a simple ratio formula of breath alcohol to blood alcohol which is 2100:1. This means that 2100 milliliters of alveolar air will contain the same amount of alcohol as 1 milliliter of blood

The Reason American Executive Sam Altman Carries a Blue Backpack Wherever He Goes

Sam Altman, the Chief Executive Officer of OpenAI which is the organization that created ChatGPT and GPT4, carries a small light blue backpack virtually everywhere he goes. This backpack serves a single function, to act as a remote detonator if ChatGPT and/or GPT4 suddenly becomes rogue and starts causing immense damage to human beings and society as a whole (e.g. causing self-driving vehicles to purposefully crash etc.). Because artificial intelligence has yet to be developed to the level that OpenAI has achieved, it is unknown as to the full potential benefits as well as risks and harms artificial intelligence may develop as more data sets are fed into it in an attempt to increase and expand upon what has already been accomplished. Despite this glaring risk, many teams around the world are working to create and improve different variations of artificial intelligence

The Difference between QR Codes and Bar Codes

The primary difference between QR code’s and barcodes is that a barcode must be read horizontally, has a maximum storage capacity of 12 – 43 characters (e.g. universal product code etc.), and can store data in one dimension, whilst a QR code is capable of being read horizontally and vertically, has a maximum storage capacity of 4000 – 7089 characters, and can store data in two dimensions as a matrix bar code. Additionally, a QR code can be 10x smaller than a bar code and still be legible and a QR code can be read if damaged or parts missing. The term “QR code” is an abbreviation for “quick response code”

How Ocean Wind Turbines Produce Electrical Energy

Wind turbines run upon a simple engineering principle which is that of wind causing the blades to turn which rotates a shift within the turbine, with this shaft producing energy for the electrical generator. This electrical energy is pumped downward, 300’ below the water surface, and into cables buried below the seabed which connect to offshore substations which then connect to onshore power stations and finally residential homes and industrial and commercial buildings. Ocean wind turbines are typically 600’ high in altitude, with spinning fiberglass blades which are approximately 240’ long, with each blade weighing up to 30 tonnes. Because of this immense size, measurements (e.g. angle of blades etc.) are crucial during the construction phase to maximize efficiency and energy output. A single revolution of a wind turbine can generate enough electricity to power an entire family home for 24 hours

American Theoretical Physicist Robert Oppenheimer’s Reaction to the First Successful Nuclear Weapon Detonation

After the Trinity nuclear launch test which occurred on July 16, 1945, the first nuclear detonation in human history, when Manhattan Project lead Julius Robert Oppenheimer was asked about the reaction of himself and others on that fateful day Oppenheimer responded, “we knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture the Bhagavad Gita. Vishnu is trying to persuade the prince that he should do his duty and to impress him takes on his multiarmed form and says, Now, I am become Death, the destroyer of worlds. I suppose we all thought that one way or another” (this phrasing/sentence structure while confusing in English, is the correct direct translation from Sanskrit)

The Etymology of the “AR15” Firearm and the Civilian AR15 vs the Military AR15

Contrary to popular belief, the civilian version of the AR15 firearm is not an assault rifle, nor does the “AR” portion of the name stand to represent the term “assault rifle”. The AR15 is named as such because it was the 15th design (e.g. the “15” portion of “AR15”) of a firearm originally manufactured by ArmaLite (e.g. the “AR” portion of “AR15”), an American firearms manufacturer which has manufactured and sold the AR15 since 1959, with the firearm first being developed in 1956. The civilian version of the AR15 firearm became available to consumers from 1963 onward. The primary difference between the militarized model and the civilian model, being the function to enable automatic fire. Once the function of automatic fire is enabled, the AR15 is considered a militarized assault rifle

The Mass Unidentified Aerial Phenomena Sighting in Nuremberg, Germany During the Renaissance

In 1561, a mass unidentified aerial phenomena sighting was documented above Nuremberg, Germany. Witnesses report observing a large black triangular object and spherical crafts falling from the sky, producing clouds of smoke. Hundreds of spheres, cylinders, and other various shaped crafts jostled erratically for 1 hour before departing. The event was described as a “battle”

The Origin of the Use of Analgesia While Giving Birth

Analgesia was not an option while giving birth until the mid 19th century as pain was believed to be a crucial part of the birthing experience. In 1591, Euphemia Maclean, a woman from Edinburgh, Scotland requested analgesia during the birth of her twins and was burned at the stake for this request. Analgesia started with Queen Victoria who used chloroform for the birth of her 8th child Leopold. It was Victoria’s experience that she told to others which made the practice catch on so quickly as Victoria felt that analgesia was an amazing invention which helped her immensely. In the 1950’s, the no medication approach swung back into fashion with Dr. Grantly Dick-Read, the first modern physician to suggest against analgesia as he believed the pain of childbirth to be psychological

Botulism Toxin (Botox) Disabling Portions of the Human Brain Related to Emotion

Because human beings interpret emotions by mirroring one another, botulism toxin, more commonly referred to by the brand name “Botox”, when injected into the forehead, alters brain activity connected with various emotional states. The temporary paralysis of facial muscles from the use of Botox disables a person’s ability to mirror the person(s) they are interacting with. It also hinders their ability to read and interpret the facial expressions of others. Surprisingly, this information is being leveraged within studies of depression and patients diagnosed with borderline personality disorder, as it is believed that temporary paralysis of the forehead may help aid those who are experiencing clinical depression and/or a borderline personality disorder
