Casting is
a manufacturing process in which a molten metal is injected or
poured into a mold to form an object of the desired shape.
Molds tend to be used to produce
products that need to be hollow in the middle, whereas dies are
used to stamp solid products out of media such as steel.
A die is a block of
metal with a special shape or with a pattern cut into it that is
used for shaping other pieces of metal such as coins or for
making patterns.
Tool and die makers are
a class of machinists in the manufacturing industries that make
jigs, fixtures, dies, molds, machine tools, cutting tools,
gauges, and other tools used in manufacturing processes.

Hemp CBD vs. Cannabis CBD
CBD (cannabidiol) oil and hemp oil are
both low in THC (delta-9 tetrahydrocannabinol), but the
difference in the amount of CBD these products contain is high.
Hemp oil usually has about 3 to 5 percent of CBD, while cannabis CBD oil has about 18 to 20 percent. It is the higher concentration that makes cannabis CBD beneficial in the treatment of various health disorders.
Hemp oil based CBD products do not contain enough of the compound to be considered much more than a health supplement. These are the products found in health food and other stores and legal in all 50 states.
Consider hemp oil-based CBD as a vitamin grade and Cannabis CBD as pharmaceutical grade.
Incidentally, Hemp CBD is regulated by the FDA as a dietary supplement, and like other dietary supplements the FDA is “not authorized to review dietary supplement products for safety and effectiveness before they are marketed.”
Hemp and marijuana are both Cannabis. Hemp is Cannabis sativa, and marijuana is either Cannabis sativa or Cannabis indica. Hemp is the common and legal term for cannabis that contains less than .3% THC. Marijuana is the common and legal term for cannabis that contains .3% and more THC.

Masons vs. Shriners
You must be a Mason to be a Shriner, but there are very many
members who just pay their yearly fee and are active in the
Shrine.
Shriners International, also commonly known as The Shriners, is a society established in 1870 and is headquartered in Tampa, Florida, USA. It is an appendant body to Freemasonry. Shriners International describes itself as a fraternity based on fun, fellowship, and the Masonic principles of brotherly love, relief, and truth.
There are approximately 350,000 members from 196 temples (chapters) - the term Temple has now generally been replaced by Shrine Auditorium or Shrine Center - in the US, Canada, Brazil, Bolivia, Mexico, the Republic of Panama, the Philippines, Puerto Rico, Europe, and Australia. The organization is best known for the Shriners' Hospitals for Children. Shriners have two claims to fame. One is acting silly and having parades with outrageous costumes and vehicles. The other is raising money to provide free medical care for children.
There are two organizations tied to the Shrine that are for women only: The Ladies' Oriental Shrine and the Daughters of the Nile. They both support the Shriners' Hospitals and promote sociability. Membership in either organization is open to any woman 18 years of age and older who is related to a Shriner or Master Mason by birth, marriage, or adoption.
The origins of Freemasonry are obscure. The best guess is that it is an outgrowth of medieval stonemasons’ guilds that began after the mid-1500s. These men, called “accepted” masons, enjoyed the ritual and secrecy that in the Middle Ages had been necessary to transmit the skills of the craft and prevent outsiders.
Eventually there were no operative masons and Masonry became a kind of fraternity, retaining such trappings of stonemasonry as the apron worn at formal functions and the familiar compass-and-square symbol. From 1740 to 1813 there were a host of Masonic rites, orders, and degrees created. These new rituals enlarged the scope of Masonry and encompassed many elaborations, some of which included elements which had previously been practiced within the craft. There are many organizations and Orders which form part of the widespread fraternity of Freemasonry, each having its own structure and terminology. Collectively these may be referred to as Masonic bodies, Masonic orders or appendant bodies of Freemasonry.
The basic unit of Freemasonry is the Masonic Lodge, which alone can initiate a Freemason. Such lodges are controlled by a Grand Lodge with national or regional authority for all lodges within its territory. A Masonic lodge confers the three masonic degrees of Entered Apprentice, Fellowcraft (or Fellow Craft), and Master Mason.
Each Masonic body sets its own membership requirements, which vary greatly. Membership is sometimes open, and sometimes invitational. In the United States, the York and Scottish Rites make petitions available to all Master Masons, but reserve the right to reject petitioners, while other groups, such as the Knight Masons, require that one be asked to join by a current member.
Joseph Smith, the first Mormon prophet had prior involvement with Freemasonry, and many of the Mormon secrets closely parallel those of the Masons, as does the notion of the ceremony’s secrecy itself.
Bottom line, all Shriners are Masons, but not all Masons are Shriners.
Incidentally, the Knights Templar membership is by invitation only and candidates are required to be Master Masons.

Turkey Facts
Turkeys are the biggest birds in their
family. On average the weight of a full grown healthy turkey can
reach up to 37 pounds (17 kilograms). Turkeys like to stay on
higher places, especially at night. Branches of trees are their
favorite sleeping places. On heights they usually keep safe from
predators like foxes, coyotes, and raccoons. They are quite
social birds and like to sleep in groups, known as flocks.
Turkey meat contains an amino acid known as tryptophan that is used to produce serotonin in our body. Serotonin is a chemical that our brain uses for relaxation and sleep functions. Of course tryptophan in turkey meat is not to blame so much as the high amount of carbohydrates that are used in making a Thanksgiving meal. Things like bread, potatoes, pies, and sweats release many kinds of amino acids in our blood. This also results in producing more serotonin with the help of tryptophan. That is why Thanksgiving meals usually make us sleepy.
Wild turkeys can fly at a speed of up to 55 mph (89 kilometers per hour) although they like to spend more time on ground finding food. Domestic turkeys like broad-breasted white turkeys can’t fly because they gain too much weight on their upper section.
Turkeys have eyes on the both sides of their head. They can see 360 degrees just by moving their head. Turkeys can also see different colors and their amazing visual abilities help them avoid sneak attacks from their predators. Their sharp eyesight helps them find their prey from a long distance.
Turkeys have no external ears, but their hearing is quite phenomenal.
Snoods are the long dangly extended flesh on the beaks of turkeys. They also have warts and dangling appendages on the both sides of their face. The colors of these snoods and warts change when the bird get excited or frightened. These usually pale pink or gray colors turn into blue, red, or white when they feel excited.

Bedspread vs. Coverlet vs. Comforter vs. Duvet vs. Quilt
A bedspread is a close relation to the coverlet
and is constructed similarly, but is designed to meet the floor.
This style adds a soft, ethereal romance to a bedroom and works
especially well in a period style home.
Coverlets differ from quilts only slightly and sometimes not at all. Coverlets typically fall a couple of inches below the mattress. Quilts contain a middle layer for warmth, coverlets may not. The purely ornamental choice can be as simple as two sheets of fabric stitched together, usually consisting of a decorative face fabric and a plain reverse fabric. Coverlets can be made loose, throw-style, semi-fitted, or fitted. The side flaps are sewn together so that the coverlet fits over the mattress like a cap. It is not designed for easy bed making or for tossing and turning under.
A comforter looks much like a duvet, except that it is decorative and all parts are integral. Its fill is more lofty than that of a quilt and comes in a wide range of densities and fiber contents. Comforters can be smooth, quilted, or shirred (gathering). Quilting and shirring help ensure the fill stays evenly distributed.
A duvet is a cotton, polyester, blended, or down feather blanket that can be used in place of upper sheet and blanket. A duvet cover is little more than a washable bag for the duvet. It is composed of two fabric sides that are joined together by a zipper, ties, or buttons. Placing a duvet at the foot of a bed is a popular stylistic choice for those who feel the pattern is too much of a good thing. On the other hand, those who opt for dual, coordinating fabrics for the face and reverse sides are rewarded with the opportunity to showcase both simultaneously if they flip the top of their duvet. With a warm layer underneath, a smaller duvet can serve as an extra comfort to the sleeper who requires a bit more warmth.
A quilt is one of the most traditional bed coverings. Before fabric was loomed in long sheets, frugal home sewers pieced together scraps of worn clothing and kitchen textiles into two sides of a blanket that sandwiched a warmth layer. Today we use batting for this layer, though in centuries past it could have been any insulating agent, from horsehair to grass. Quilting is also a term for the designs created by threads as they bind together the two fabric layers and the internal layer of any bed covering. This means that quilting is not limited to quilts: Duvets can be quilted, as can comforters.
Incidentally, matelasse is a special type of fabric made in the French tradition with a jacquard loom that gives a tufted look and can be made into comforters, duvet covers, coverlets, and quilts. The term simply refers to a cotton fabric with a raised design.

Super Brain Computer
Researchers at Manchester
University have just switched on the world’s largest
neuromorphic supercomputer. While a neuromorphic supercomputer
may be the closest thing we have to an artificial brain, we are
still a long way off from building the huge head-shaped computer
from The Matrix: Revolutions - which is a good thing.
A neuromorphic supercomputer mimics the biological neural activities of a human brain by emitting spikes of pure electro-chemical energy. To achieve this, scientists at Manchester University built the computer with one million processors at its core.
So far SpiNNaker is able to make 200 trillion actions per second and it took ten years to build.

Hereditary Titles
Hereditary titles have a hierarchy
known as the five grades or ranks of the peerage, just as in
various other European countries. The highest grade is
duke/duchess, followed by marquess/marchioness, earl/countess,
viscount/viscountess, and baron/baroness.
Dukes and duchesses are addressed with their actual title, but all other ranks of the peerage are addressed as Lord or Lady. Non-hereditary life peers are also addressed as Lord or Lady.
Life peers are appointed members of the peerage whose titles cannot be inherited, in contrast to hereditary peers. In modern times, life peerages, always created at the rank of baron, are created under the Life Peerages Act 1958 and entitle the holders to seats in the House of Lords, presuming they meet qualifications such as age and citizenship. The legitimate children of a life peer are entitled to style themselves with the prefix "The Honourable", although they cannot inherit the peerage itself.
Lord and Sir are two titles that show difference between them in terms of their significance and application. Lord is an inherited title or given by a government. A Lord can occupy the seat of the House of Lords.
Sir refers to the Knight, so it is an honor of Knighthood bestowed on an individual by the Queen. The title of Sir is lower rank of nobility when compared to the title of Lord. These are individuals who have made outstanding contributions in their field and have been awarded official honors in the name of the reigning monarch. There are different categories, but only those receiving the highest level of award are entitled to use the title Dame or Sir.
The fashion designer Sir Paul Smith, for example, received a knighthood in 2000 from Queen Elizabeth II, while actress Dame Judi Dench received the female equivalent of a knighthood in 1988 – Dame Commander of the Order of the British Empire. Elton John (Reginald Kenneth Dwight) was knighted by Elizabeth II for "services to music and charitable services" in 1998.

AR vs. MR, vs. VR
AR is augmented reality. If virtual reality is total
immersion, augmented reality is all about layering virtual
elements onto the real world. Pokémon Go is probably the most
well-known example of this technique, with a nexus of magical
animals layered onto a real-world map and what you can see with
your phone’s camera.
Until recently, AR has been distinguished by a level of disconnect between the virtual and real world. You may have information imposed on your field of vision – like images or text, but these virtual elements are not anchored to the real world, and do not respond to physical objects in real-time.
Devices such as Google Glass were early attempts to integrate AR into headwear, but while there are reports that Apple is working on hardware dedicated to AR, and there are some crazy patents about AR contact lenses, the current mode for AR is to layer virtual elements using pre-existing devices such as smartphones and tablets.
MR is mixed reality. Mixed reality involves a strong element of interaction between physical and digital elements. The clearest case of this is Microsoft’s HoloLens, which can impose virtual models of buildings, bodies, and vehicles that designers can walk around, inspect and tweak as they see fit. Experimental hardware such as the Magic Leap and Intel’s Project Alloy prototype have given a glimpse of where this path could lead, potentially encompassing elements like haptics (touch).
The lines between AR and MR have blurred somewhat. You could argue the IKEA app, for example is a form of mixed reality as it allows users to walk around virtual furniture on a real-world carpet, as it if were a physical object. Some say MR is another way of saying ‘“true AR”. It is likely that, as digital-physical interactions become more sophisticated, one term will likely take over the other. Many believe mixed reality will prevail.
VR is virtual reality. It is most often used as an umbrella term for many immersive, computer-simulated environments. This means that you can probably get away with calling AR and MR subsections of VR.
Virtual reality is a totally computer-simulated version of reality (for sound and vision). Head-mounted displays like the Oculus Rift, HTC Vive, and PlayStation VR, as well as mobile-based headsets like Google Daydream and Samsung Gear, are all VR hardware. You strap them onto your face, and are immersed in a digital environment. Another subsection of VR is 360-degree video. Special cameras capture these images, so they are not computer-made virtual environments, but you still experience them using a VR headset.
Ideally, a VR user should feel like they have been transported from their living room into a totally different space. Having your field of vision taken up by a virtual world can trick your brain into feeling physically present within that reality. These ideas about presence and immersion and the potential for VR to communicate another person’s perspective, making a user feel physically involved in a way screen-based film cannot.
None of these should be confused with AI, artificial intelligence, which is a totally different topic.
