0:00 Intro to welding basics
0:17 What is welding?
0:47 What is MIG welding?
1:15 What is stick welding?
1:59 What is TIG welding?
2:47 What type of welder should you buy?
3:20 What metals should you use with each welder?
Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials being bonded without heat, and solid-state welding processes which bond without melting, such as pressure, cold welding, and diffusion bonding
Metal welding is distinct from lower temperature bonding techniques such as brazing and soldering, which do not melt the base metal (parent metal) and instead require flowing a filler metal to solidify their bonds.

Biden appears to be lost and confused at the 50th G7 summit in Italy
Italian Prime Minister Giorgia Meloni was seen grabbing Biden to bring him back to the group.
The Group of Seven (G7) is an intergovernmental political and economic forum consisting of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States; additionally, the European Union (EU) is a "non-enumerated member". It is organized around shared values of pluralism, liberal democracy, and representative government. G7 members are major IMF advanced economies.
Originating from an ad hoc gathering of finance ministers in 1973, the G7 has since become a formal, high-profile venue for discussing and coordinating solutions to major global issues, especially in the areas of trade, security, economics, and climate change. Each member's head of government or state, along with the EU's Commission President and European Council President, meet annually at the G7 Summit; other high-ranking officials of the G7 and the EU meet throughout the year. Representatives of other states and international organizations are often invited as guests, with Russia having been a formal member (as part of the G8) from 1997 until its expulsion in 2014.
The G7 is not based on a treaty and has no permanent secretariat or office.

A Chameleon changes color out in the wild of Madagascar
A Chameleon changes color out in the wild of Madagascar
Chameleons change color by dispersing or concentrating pigment granules (melanophore cells) in the cells that contain them. In general, the animal appears lighter-coloured when pigment is concentrated and dark when pigment is dispersed throughout the cells. The chameleon's colour state at any given time is controlled by a complex interaction of hormones, temperature, and the animal’s autonomic nervous system.
https://www.britannica.com/story/how-do-chameleons-change-colour
Chameleons or chamaeleons (family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 200 species described as of June 2015. The members of this family are best known for their distinct range of colours, being capable of colour-shifting camouflage. The large number of species in the family exhibit considerable variability in their capacity to change colour. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of colour-combinations (reds, yellows, greens, blues) can be seen.

The Steel Making Process From Start to Finish - Material Science
The Steel Making Process From Start to Finish
Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost, steel is one of the most commonly manufactured materials in the world. Steel is used in buildings, as concrete reinforcing rods, in bridges, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons.
Iron is always the main element in steel, but many other elements may be present or added. Stainless steels, which are resistant to corrosion and oxidation, typically need an additional 11% chromium.
Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace.
The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron.
Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed. The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled and screened into pieces ranging from one inch to four inches. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong. The strong pieces of coke with a high energy value provide permeability, heat and gases which are required to reduce and melt the iron ore, pellets and sinter. Today, natural gas is increasingly being added in place of coke to the same degree in the blast furnace to reduce carbon emissions

Starship’s Super Heavy Booster landing burn and soft splashdown in the Gulf of Mexico June 6, 2024
Starship’s Super Heavy Booster landing burn and soft splashdown in the Gulf of Mexico !!
Starship survives reentry during fourth test flight
Test Flight 4 Starship Heavy 1st stage slashdown landing in the Gulf of New Mexico on June 6, 2024. The upper stage landed later in the Indian Ocean
CAPE CANAVERAL, Fla. — SpaceX conducted the fourth test flight of its Starship launch system June 6, with both the Super Heavy booster and Starship upper stage making it back to the surface intact.
The vehicle lifted off at 8:50 a.m. Eastern from the company’s Starbase test site at Boca Chica, Texas. The ascent appeared to go as planned other than the failure of one of 33 Raptor engines in the Super Heavy booster to ignite.
During the booster’s final phase of descent, it reignited three Raptor engines for a landing burn. This allowed the booster to make a “landing” in the Gulf of Mexico, reducing its velocity to zero at the ocean surface before toppling over. Achieving that landing was a major priority for the mission

Scanning electron microscope images of microbes
What Are Microbes? Microbes are organisms that are too small to be seen without using a microscope, so they include things like bacteria, archaea, and single cell eukaryotes — cells that have a nucleus, like an amoeba or a paramecium. Sometimes we call viruses microbes too.

Petroleum - oil - refining processes explained
Petroleum refining processes explained
How crude oil is refined into petroleum products
Petroleum refineries convert (refine) crude oil into petroleum products for use as fuels for transportation, heating, paving roads, and generating electricity and as feedstocks for making chemicals.
Refining breaks crude oil down into its various components, which are then selectively reconfigured into new products. Petroleum refineries are complex and expensive industrial facilities. All refineries have three basic steps:
Separation
Conversion
Treatment
Separation
Modern separation involves piping crude oil through hot furnaces. The resulting liquids and vapors are discharged into distillation units. All refineries have atmospheric distillation units, but more complex refineries may have vacuum distillation units.

Footage of the tallest man to ever live, Robert Wadlow
Footage of the tallest man to ever live, Robert Wadlow
Robert Wadlow (February 22, 1918 – July 15, 1940), also known as the Alton Giant and the Giant of Illinois, was an American man who was the tallest person in recorded history for whom there is irrefutable evidence. He was born and raised in Alton, Illinois, a small city near St. Louis, Missouri
Wadlow's height was 8 ft 11.1 in (2.72 m) while his weight reached 439 lb (199 kg) at his death at age 22. His great size and his continued growth in adulthood were due to hypertrophy of his pituitary gland, which results in an abnormally high level of human growth hormone (HGH).
