3. Maths in Biotechnology
• Mathematical areas like calculus, probability
theory, linear algebra, abstract algebra, graph
theory, algebraic geometry, topology, dynamical
systems, equations and coding theory are applied
in bio- technology.
4. Maths in Astronomy
Astronomers use maths all the time
It is used to perform calculations when we look at the objects in the sky with a telescope
Astronomers use maths when they are forming theories for the physical laws that govern the
objects in the sky Some interesting facts
The remaining lifetime of the Sun is 4.76 10^9 years Our galaxy milky way is about 100 103
light years wide
Moon is about150 million km from the sun
The diameter of our planet Earth is 12742 km
Temperature of the core of the Earth is 6000 Celsius
5. Maths in Mechanics
Mechanical Engineers use Maths with analytical and problem solving abilities to develop or
repair new machines
Basic maths, calculus and trigonometry are important maths skills required for a Mechanical
Engineer
The general study of the relationship between motion, forces and energy is called Mechanics
Examples of application of maths in mechanics
Speed is measured as distance travelled / time taken
Force exerted = Mass x Acceleration
Gravity of Earth is 9.8 meters/second
6. Maths in Chemistry
• Mathematics is used widely in chemistry as well as
all other sciences
• Mathematical calculations are absolutely necessary
to explore important concepts in chemistry.
• Without some basic mathematics skills, these
calculations, and therefore chemistry itself, will
be extremely difficult
• Scientists put only the digits they can reasonably
be certain of in their numbers. They might say, for
example, that they measured "10" cm (note the
presence of the decimal point).
7. Maths in Medicine
• The Human body is the entire structure of a human being and
comprises head, neck, trunk, arms, hands, legs and feet
• Every part of the body is composed of various types of cell
• At maturity the estimate number of cells in the body is
given as 37.2 trillion.
• In our body there are 206 bones, the temperature of the
normal human body is 98.0
• The blood pressure of our body is 120 or over 80, our brain
uses 20% of the total oxygen and blood in our body etc
8. Maths in electronics
Analytic geometry uses numerical techniques to describe classic geometric concepts including
lines, points and curves
Analytic geometry uses numerical techniques to describe classic geometric concepts including

Kilowatt Hours - Unit of energy equal to 3.6 mega joules or 1000 watt hours
OHM - The SI unit of electrical resistance between two points of a conductor with a difference
of 1volt
Voltage (Volt) - The SI unit of volts across a conductor when a one ampere current dissipates
onewatt of power
Watt-Derived unit of power that measures the rate of energy conversion defined in one joule
per second
Kilowatt-Measure of 1000 watts of standard electrical power or an energy consumption rate of
1000 joules
Megavolt - Measure of 1 million Watts of standard electrical power or one joule per second
9. Maths in Physics
Physics is probably the one area of science where many aspects of maths has been directly
applied
Some of the important in Physics are
(1)Classical Mechanics (Calculus)
(2)Electro Magnetism (Vector Calculus)
(3)General Relativity (Differential Geometry)
(4)Quantum Field Theory (Matrices, Group Theory)
(5)Superstring Theory (Know Theory)
10. Maths in Everyday
Life
We apply
mathematics
in simple
activities
that we do
every day
Our mother
uses the
concept of
ratios and
proportion
during
cooking
Ratio is used
to compare
quantities
Proportion is
used along
with ratio
when the
quantity of
ingredients
increases
