The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
Thermodynamic work is one of the principal kinds of process by which a thermodynamic system can interact with and transfer energy to its surroundings. This results in externally measurable macroscopic forces on the system's surroundings, which can cause mechanical work, to lift a weight, for example, [1] or cause changes in electromagnetic, [2] [3] [4] or gravitational [5] variables.
Gopal Pandey (1883–1914) was the first person to write a book in Nepali about mathematics. He wrote four editions of his book in Nepali. The third edition was also published in Hindi. He was honoured as the Royal Astrologer for successfully predicting the number of lunar eclipses in 1884. He was also responsible to make the plot of Tudikhel. [9]
Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: P = d W d t = F ⋅ v {\displaystyle P={\frac {dW}{dt}}=\mathbf {F ...
Fermi estimates generally work because the estimations of the individual terms are often close to correct, and overestimates and underestimates help cancel each other out. That is, if there is no consistent bias, a Fermi calculation that involves the multiplication of several estimated factors (such as the number of piano tuners in Chicago ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
The parliamentary act, established by the Nepalese government on June 17, 2010, based on the concept of a multi-university system, is a state-backed institution based on land donated by the Nepalese government.
The data will be processed to calculate the potential to exploit solar radiation to meet the energy demand of the country. Energy Auditing and Conservation in order to minimize the energy waste. Energy Auditing is the tool used for the purpose. Diversification of Solar Technology. The activity covers activities such as proliferation of ...
