| RuBot II - The Rubik's cube solving robot. |
 |
Read this before you comment! This is the new
version of RuBot by Pete Redmond from Dublin,
Ireland. It's very different to the
prototype but it has to be the coolest
looking robot solver ever. There are cameras
in the eyes of the head that scan the cube
before the pneumatic arms solve it. It
usually solves the Cube in about 35 seconds
(not including the scan) no matter how much
it is mixed up.
The solving algorithm is taken care of by
Herbert Kociemba's Cube Explorer software and
usually solves the cube in a maximum of about
20 moves. In this video, the cube wasn't
mixed up too hard so RuBot was able to find
the optimum solution.
Thanks to all of those who think it is too
good to be true. That is a real compliment!
If you still don't believe it, Look at the
other RuBot videos - they have better
scrambles. Or better still, call in on one
of RuBot's live demonstrations. By the way,
that's my daughter in the clip with RuBot.

| Algebra: Solving Linear Equations -- Part 1: The Basics |
 |
[NOTE: This video is only the first 18
minutes of the full lesson, please visit my
website to purchase complete version] Lesson
consists of providing you with a
Self-Tutorial on how to solve linear
equations. Tutor discusses what is an
Equation, Solution, Solution Set, Equivalent
Equations, Identity, Contradictions,
Conditional Equations, Linear Equations, the
Standard Form of a Linear Equation. I show
you how to actually SOLVE linear equations
going step-by-step. I don't skip steps. I
review some of the properties of Equality
here too. I remind you to check the work done
and how to solve linear equations using a
calculator. At the end, you will know how to
easily solve equations that look like:
2[y - (4y - 1)] = 5 - 9y
No word problems are done here. This is shown
in DETAIL in Part 2 of the Lesson.

| NEEM - A Tree For Solving Global Problems |
 |
Neem (Azadirachta indica) has worldwide
medicinal and agricultural applications as a
non-toxic alternative to synthetic chemicals
for both curing and preventing disease.
MEDICINAL uses of neem:
ANTIPATHOGEN- effects are selective against
parasites: INSECTS (eg Head Lice, Whitefly,
Weevil, Caterpillars, Fleas, Moths), WORMS,
FUNGI (eg Athletes Foot, Yeast Infection),
BACTERIA (eg Leprosy, Tuberculosis) and VIRUS
(eg Malaria, Flu)
IMMUNO-MODULATOR,
ANTICANCEROUS,
ANTIVIRAL,
ANTIFUNGAL,
ANTIALLERGEN,
ANTIDIABETIC,
CNS EFFECT,
ANTIHEPATOTOXIC (liver),
WOUND HEALING,
CARDIO-VASCULAR,
SKIN DISEASES (eg eczema, psoriasis),
ANTI-HEMORRHOIDS,
ANTI-PYRETIC (fever),
ANTI-HISTAMINE,
ANTI-ARTHRITIC,
ANTI-INFERTILITY,
CONTRACEPTIVE,
ANTI-OXIDANT,
ANTI-LEPROTIC,
AGRICULTURAL uses:
STORAGE OF GRAINS
WOOD
FISHERIES
PESTICIDE (kills Threadworms (Nematodes),
repels Slugs and snails, but is beneficial
for spiders, bees, wasps, ladybirds, birds,
bats and earthworms)
ANTI-AFLATOXIN (toxin produced by fungus on
many common commercial crops such as cotton)
FERTILISER
FORESTRY uses: Improvement of soil, Wind
breaker, Mulching...
HOUSEHOLD: Pest repellent, Fuel, Soap...

DOCUMENTARIES
1. The Nature of Things with David Suzuki
(1994)
This 46-minute film focuses primarily on the
use of neem as insecticide and the discovery
of Azadirachtin:
Neem Trees are used for reforestation,
because it can grow well in dry conditions
and sheds leaves all year round.
Neem is mentioned in the Indian Vedas. Neem
is beneficial for all human skin disorders,
the skin of animals and plants and the skin
of the Earth.
Neem sticks are used as tooth brushes, and
neem extracts in toothpaste. Cavities &
Periodontitis are caused by bacteria which
are killed by neem (ANTIBACTERIAL). Neem is
ANTI-INFLAMMATORY & ANTI-ULCEROGENIC (cures
inflammation and ulcers).
Fed to livestock it is nutritious, medicinal
and ANTHELMINTIC (expels parasitic worms).
It is part of sustainable agriculture as a
fertilizer & pesticide. Totally non-toxic to
plants, people, birds, fish.
In the fight against malaria, neem acts both
as insect repellent & an ANTIMALARIAL
(anti-viral oral treatment for infection and
relief of symptoms).
Alternative to conventional pesticides (more
effective, non-toxic, selective). There is no
need for farmers to isolate active
ingredients for synthesis. Neem contains
hundreds of beneficial compounds complete
with packaging. Why were attempts made by
large pharmaceutical companies to restrict
its use?
2. The Corporation (Mark Achbar 2003)
Vandana Shiva talking about freedom from
intellectual property laws. Governments and
corporations were restricting use of Neem, so
people all over the world successfully fought
back.
THE CHALLENGE NOW FOR NEEM- is against
monoculture plantation projects that are
funded by corporations. Neem has an
invaluable role in the biodiversity of our
Ecosphere. To grow it in isolation does not
benefit other plants or the Neem Trees.. We
must cultivate healthy Wild Neem Trees which
live with other wildlife and help to support
it. Large Corporate Neem Plantations damage
land and produce inferior trees, while paying
workers slave wages.
THE PROBLEMS WITH PLANTATION NEEM-
Neem's ability to hold water may cause damage
to the water table,
The collection of nutrients on top soil may
cause salination of the soil.
The neem trees do not have optimal conditions
to mature properly and do not generate the
same variety of active components.
The land is owned by corporations, who do not
pay workers a fair wage.
