Infographics
มุมมอง 1828 วันที่ผ่านมา
Infographics are visual representations of information, data, or knowledge that use a combination of graphical and textual elements to make complex topics easy to understand. Creating an infographic requires deliberate considerations of key elements from source material. This video discusses the conception and designing process, while comparing two infographics.
Minerals
มุมมอง 823หลายเดือนก่อน
Minerals must be naturally occurring, inorganic solids with distinct chemical compositions and physical properties, as well as an orderly arrangement of atoms within a crystalline lattice. Many thousands of minerals exist, but only several dozen are especially common. These include minerals such as Quartz, Graphite, Potassium Feldspar, and Fluorite. We use minerals every day and are dependent u...
Galena
มุมมอง 5Kหลายเดือนก่อน
This is the mineral Galena. It has a metallic luster and a dark grey to black streak. Galena contains only 2 elements, Lead and Sulfur, and has the chemical formula PbS. It thus belongs to the Sulfide chemical family. Sulfides are minerals consisting of Sulfur and one or more metals. It ranks 2.5 on Mohs hardness scale, which is relatively soft and about as hard as your fingernail. Thus, Galena...
Talc
มุมมอง 191หลายเดือนก่อน
This is the mineral Sulfur. Note that it’s classified as a Native Element Mineral. Native Sulfur has all the characteristics required of minerals. Minerals must be naturally occurring, inorganic solids with distinct chemical compositions and physical properties, as well as an orderly arrangement of atoms within a crystalline lattice. Since Sulfur has all these characteristics, it’s rightfully c...

Quartz
มุมมอง 123หลายเดือนก่อน
This is the mineral Quartz. It has a specific gravity of 2.6 and a vitreous luster. Vitreous simply means that quartz often looks like glass. Its white streak contrasts well against a black ceramic streak plate. Quartz is composed of the two elements Silicon and Oxygen, and thus belongs to the Silicate chemical family. Note that Oxygen and Silicon are the two most abundant elements in Earth’s c...
Pyrite
มุมมอง 1.7Kหลายเดือนก่อน
This is the mineral Pyrite. It has a striking brass and yellow metallic luster but produces a brown or greenish black streak when drawn across a white ceramic streak plate. It’s a relatively dense mineral, with a specific gravity of about 5, thus making it feel heavy in your hand. It ranks between 6 and 6.5 on Mohs hardness scale. Pyrite can be scratched by Quartz, which ranks 7, but not by Apa...
Potassium Feldspar
มุมมอง 144หลายเดือนก่อน
This is the mineral Potassium Feldspar. It is also called K-Feldspar, because K is Potassium’s symbol on the Periodic Table. You may also hear it called Orthoclase Feldspar, or simply Orthoclase. It’s one of Earth’s most abundant rock-forming minerals. Like most other rock-forming minerals, it belongs to the Silicate chemical family because it contains repeating chains of linked Silicon and Oxy...
Olivine
มุมมอง 96หลายเดือนก่อน
This is the mineral Olivine. It’s a common rock-forming mineral that belongs to the Silicate chemical family because it contains repeating chains of linked Silicon and Oxygen tetrahedra. These tetrahedra consist of a single, central Silicon atom surrounded by 4 Oxygen atoms. In Olivine’s case, these Silicon and Oxygen tetrahedra are bound to atoms of Magnesium or Iron. Olivine that contains Iro...
Muscovite
มุมมอง 142หลายเดือนก่อน
This is the mineral Muscovite. It has a vitreous, or glassy, luster that is especially visible on its crystal faces. A crystal face is a geometric plane that develops as a crystal grows. Muscovite’s crystal faces are flat, sheet-like planes that look glassy under reflected light. The mineral exhibits perfect basal cleavage, meaning that it splits parallel to other cleavage planes. It ranks betw...
Magnetite
มุมมอง 1.8Kหลายเดือนก่อน
This is the mineral Magnetite. It has a metallic luster and a black streak that is best seen when drawn across a white ceramic streak plate. It’s positioned about mid-range on Mohs hardness scale, ranking between 5.5 and 6.5. The mineral has a specific gravity of 5.2 and thus feels relatively heavy in your hand. Magnetite has no cleavage. Its chemical formula is Fe3O4, making it part of the Oxi...
Hematite
มุมมอง 1.6Kหลายเดือนก่อน
This is the mineral Hematite. Some specimens exhibit a metallic luster, while others clearly display an earthy luster. Metallic varieties rank between 5 and 6 on Mohs hardness scale, while earthy varieties are much softer and often have a hardness rank less than 2. In either case a high contrast, reddish-brown streak is produced when a sample is drawn across a white ceramic streak plate. The mi...
Halite
มุมมอง 382หลายเดือนก่อน
This is the mineral Halite. It’s commonly called Rock Salt, or simply Salt, and is usually clear or white with a vitreous, or glassy, luster. Some specimens faintly exhibit a yellow, red, or even bluish tint. It’s a relatively soft mineral, ranking 2.5 on Mohs hardness scale. Thus, Halite can scratch Gypsum, which is ranked 2, but not Calcite, which is ranked 3. When drawn across a black cerami...
Gypsum
มุมมอง 203หลายเดือนก่อน
This is the mineral Gypsum. Gypsum belongs to the Sulfate chemical family. Sulfate minerals contain a Sulfate ion. Sulfate ions are tetrahedral shaped compounds consisting of a central Sulfur atom surrounded by 4 Oxygen atoms. It often exhibits a vitreous, or glassy, luster, but some specimens display pearly or dull lusters. For example, the crystalline variety of Gypsum called Selenite has a p...
Graphite
มุมมอง 1.8Kหลายเดือนก่อน
This is the mineral Graphite. Note that it’s classified as a Native Element Mineral because it's entirely composed of just one element, Carbon. Graphite has all the characteristics required of minerals. Minerals must be naturally occurring, inorganic solids with distinct chemical compositions and physical properties, as well as an orderly arrangement of atoms within a crystalline lattice. Since...
In meteorites magnetite looks super cool great video
instead of nested IF function, you could use vlookup.
Thanyou sir to known about how draw the isobar❤️❤️❤️
How I can sell my pyrite
Is there a specific way I need to format my CSV file BEFORE I export it to make sure it's compatible to open in Google Earth Pro?
Selamat pagi...saya dari Indonesia. Saya memiliki beberapa batu meteorite yang ingin saya jual. Apa anda berminat???
Sir, how we can increase decimal precisions of google earth place mark values.? can u please explain.?
Thanks for this clear, precise, simple intros into minerals! Appreciate it.
Very nice 👍
Is there any value for galena
Looks like the blue skystone. They claim it also is composed of mostly oxygen. Mmmm i wonder???🤔🤔🤔
Buy Silver , Platinum, & Crystalized Osmium.
just where do i get the illinois ethanol plants.csv file from ?? on the atlas.eia.gov list there are many files but not that one !!! also by following your instructions the "fields" that open when i've downloaded my csv file from INFORAD K1 device have different selections than the blurry ones in your blurry video... so it's hard to see what corrections i have to do.. your don't touch anything comment doesn't work....unless these field settings are automatically loaded from the csv file ? is that why we need the illinois ethyanol plants.csv file ? you've done half the job..... shown us it's possible, but with files we cant find, blurry video we struggle to read... how about giving us a better explination with good images please...
I'm wondering the same thing!
It changes font size for existing labels but not for place marks I add myself.
how did u get the capacity factor?
Sir do u have video on calculations of gas and oil fired power plants ? I need plz help

The granite is so porous that it’s absorbing the water just as it would soundwaves.
This would seem to be a better fit for some gis software, there is even qgis which is open source and totally free. It seems like it would be easier for us
i add new icon but when i send this file in kml file to other he dont see my icon it show only X plz helpp
You have to save as "kmz". kmz includes the icon, kml does not.
что о этих принципах кто то что то ещё незнает ??? и хочу подметить что данная технология является тупиковой и крайне неэффективной !!

Theodore, this has really helped me out. Thank you.
How to group points by zones?
I attached a motor to my Axial flux motor but it’s very difficult to turn. My configuration is 3 phase, 6 coils connected to 3 bridge rectifiers that are connected to a capacitor to smooth out the power. Turning by hand I get 12 volts. When I connect a DC motor it’s hard to turn the Axial flux motor. Any reason why this is?
If you have time, can you explain the diffrence between connecting just the one phase to the rectifier as to spliting the wire?
