What I’d like to do this week is talk about another popular credo‚ one that plays a very large role in blinding people nowadays to the shape of the future looming up ahead of us all just now. In an interesting display of synchronicity‚ it came up in a conversation I had while last week’s essay was still being written. A friend and I were talking about the myth of progress‚ the facile and popular conviction that all human history follows an ever-ascending arc from the caves to the stars; my friend

and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes. Animal Cell Plant Cell Cell wall Absent Present (formed of cellulose) Shape Round (irregular shape) Rectangular (fixed shape) Vacuole One or more small vacuoles (much smaller than plant cells). One‚ large central vacuole taking up 90% of cell volume.

THE SOLAR SYSTEM T The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it‚ all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system’s mass (well over 99%) is in the Sun. Of the many objects that orbit the Sun‚ most of the mass is contained within eight relatively solitary planets whose orbits are almost circular and lie within a nearly flat disc called the ecliptic

The Cultural and Economic effect of Solar Panel Technology on our Society. Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C‚ when the sun’s heat was concentrated by glass and mirrors to light fires. Today‚ we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental‚ economic‚ psychological and ethical implications for our

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

Advantages Solar cells provide cost effective solutions to energy problems in places where there is no mains electricity. Solar cells are also totally silent and non-polluting. As they have no moving parts they require little maintenance and have a long lifetime. Compared to other renewable sources they also possess many advantages; wind and water power rely on turbines which are noisy‚ expensive and liable to breaking down. Rooftop power is a good way of supplying energy to a growing community
