A man leaps off of a 12m building into a large, 4 meter tall vat of quicksand. The man leaves the roof with a horizontal velocity of 18.0 miles per hour. ( 1.000 mi/hr = 0.4470 m/s ). Q1: A robot on the ground believes that the man is going to miss his mark, andContinue reading “KINEMATICS: A Leap of Faith”

RADIANT ENERGY: Wavenumber, Angular Frequency, and the Wave Nature of Light
Trigonometric functions such as sin ( θ ) and cos ( θ ) are commonly used to model the oscillating motion of traveling waves. In the diagram above, a complete wave cycle occurs from crest-to-crest, trough-to-trough, or along the x-axis as indicated by the blue line. Since the diagram above can be modeled with theContinue reading “RADIANT ENERGY: Wavenumber, Angular Frequency, and the Wave Nature of Light”
CHEMISTRY: A Review of Molarity ( M ), Balanced Chemical Reactions, Limiting Reagents, and Quantitative Analysis
Balanced chemical reactions ( RXN ) represent reactions in which perfect ratios of reactants and products react. Let’s consider a photosynthetic RXN where glucose reacts with molecular oxygen to form carbon dioxide, water, and energy: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy In the subatomic world, a single molecule of glucose reacts withContinue reading “CHEMISTRY: A Review of Molarity ( M ), Balanced Chemical Reactions, Limiting Reagents, and Quantitative Analysis”
STOICHIOMETRY: Balancing Chemical Reactions
Stoichiometry is founded upon the law of the conservation of mass. A chemical reaction’s ( RXN ) reactants and products must be balanced in such a way that a rearrangement of atoms ( or molecules ) occurs, but the total mass of atoms involved in the RXN is conserved. Let’s begin with an examination ofContinue reading “STOICHIOMETRY: Balancing Chemical Reactions”
THE BASIC STRUCTURE and FUNCTION of DNA and RNA:
DNA vs. RNA STRUCTURE Deoxyribonucleic acid ( DNA ) and Ribonucleic acid ( RNA ) enable the cells of living organisms to manufacture proteins. Proteins can exist as singular or multi-strand molecular units with very complex functions; they can be used to form structural cell wall components, neurotransmitters, enzymes, and other structures necessary for anContinue reading “THE BASIC STRUCTURE and FUNCTION of DNA and RNA:”
KINEMATICS: The ” architecture of motion. “
Q: A mass m is moving horizontally across the surface of the earth with a velocity of ( v ) = 30 m/s . The mass approaches a ledge with an edge situated 100 m above the ocean. The mass eventually moves off the ledge and falls until it reaches the ocean’s surface. Calculate theContinue reading “KINEMATICS: The ” architecture of motion. “”
CRYPTOCURRENCY AND THE ECONOMIC TRANSFORMATION OF AFRICAN COUNTRIES:
Have you every looked at money and wondered how long it has been circulating, where all it has been, and within whose hands it has travelled? Additionally, how many of us have been on the receiving end of counterfeit money that made its way through money channels without being noticed? All of the money we’veContinue reading “CRYPTOCURRENCY AND THE ECONOMIC TRANSFORMATION OF AFRICAN COUNTRIES:”
BUYING AND ” HODLING ” CRYPTOCURRENCY: 101
Several mistakes are commonly made by new cryptocurrency investors. For starters, it is wise to make a definitive choice between investing vs. active trading. Taxes, transaction fees ( and losses ) quickly add for active cryptocurrency traders. Additionally, the sale of any cryptocurrency that occurs when a coin has been held less than 1 yearContinue reading “BUYING AND ” HODLING ” CRYPTOCURRENCY: 101″
MARKET ORDERS, LIMIT ORDERS, and STOP-LOSS ORDERS: What are the differences?
Investors most commonly use market orders to buy or sell shares of a company’s stock. A market order allows a desired stock trade to be executed immediately if a buyer or seller becomes available. This happens very quickly during trading hours if large numbers of investors continuously buy and/or sell a stock during market hours.Continue reading “MARKET ORDERS, LIMIT ORDERS, and STOP-LOSS ORDERS: What are the differences?”
FINDING THE LOWEST COMMON DENOMINATOR ( LCD ) OF FRACTIONS AND DETERMINING THE TOTAL RESISTANCE ( Rt ) OF PARALLEL ELECTRICAL CIRCUITS:
FINDING THE LOWEST COMMON DENOMINATOR: Let’s first envision putting two half pieces of a pie together to get a full pie. Numerically, this would involve adding ( 1/2 ) + ( 1/2 ) = ( [ 1 + 1 ] / 2 ) = ( 2/2 ) = 1 whole pie. This example was madeContinue reading “FINDING THE LOWEST COMMON DENOMINATOR ( LCD ) OF FRACTIONS AND DETERMINING THE TOTAL RESISTANCE ( Rt ) OF PARALLEL ELECTRICAL CIRCUITS:”
