What is the definition of Causality?

The definition of Causality is the relation between a cause and effect. Causality is sometimes referred to as cause and effect relationship. If the cause-and-effect relation is high, then the causality is high. Likewise, if the cause-effect relationship is low, the causality is low.

Why is Causality important?

Causality and learning about cause and effect is very important in life. In order to do anything in life, you need to know what will cause the thing you want to achieve to happen.

For example, Dan wants to go to John’s birthday party. That is the effect. Now, Dan must think about what must be done to cause the effect. In another word, what must be done so that Dan can go to John’s birthday party. Dan can bribe Dan’s big brother to drive him. Or, Dan can do all of his own his experiments and ask his parents nicely. Whatever Dan decides to do is the cause and going to John’s party is the effect.

Example of Causality or cause-and-effect relationships

A baby learns the concept of causality at a very young age. Although babies cannot use words to communicate, babies cry to get adults’ attention. Babies know that crying will bring about the effect.

A tennis player hitting the ball causing the tennis ball to go to the other side of the court. In this case, hitting the ball is the cause, the ball going to the other side of the court is the effect.

Heat causes people to sweat. In this case the high temperature is the cause and the effect is people sweating.

Falling down a tree causing a boy to break his arm. In this case, the boy falling off a tree is the cause, breaking his arm is the effect.

Causality and Experiments

Causality and Science Experiments are closely related. People conduct Science Experiments so that they may understand how things work. In doing Science Experiments, they change one variable at a time to understand what happens when that variable is changed. This is basically the study of cause and effect or causality.

Question: Are their some scientist warning us regarding the CERN anti matter experiment?

The experiment will be turned on Wednesday , but the collision won`t be done until October. What I have been reading is that this could change our knowledge about science or it could destroy our planet. Everyone should really follow this story.

Answer: “it could destroy our planet”
Anyone who is saying that is not a scientist and does not know what they are talking about.

There are particles more energetic than will be created in the LHC striking the upper atmosphere all the time.

The advantage of conducting this experiment is that it will be under controlled conditions where the results can be measured. We will learn new things about matter and the universe by doing this.

What is the point?

Think about this.
If the dinosaurs had a nuclear physics research program, they would still be here.

Question: is tv really that bad for toddlers?

sometimes it irritates when some parents would say that they’re no good and that they don’t really learn from them.. and that the best way for a child to learn is to interact with mom or dad.. so?? does this mean that i’d be facing our toddler 12 hrs a day? because tv is really no good for them?

when i put the tv on for her.. it would be those shows that are educational. like super why..(reading/spelling).. sid the science kid (they do experiment)… and barney/sesame street/play with me sesame..

she’ll probably takes a total of 2-2.5 hrs of watching tv.. all broken up. and now, i’m thinking of buying some math dvd’s for her.. would it make her not learn at all?? coz according to them, they don’t learn anything from t.v. (tho our daughter learned to read by watching dvd on reading.. first it was just memorization but then, it’s indeed phonetic patterns..[i remember when she tried to read the word success, she said 'soo sess')]

Answer: Some shows aren’t bad for kids, but others can be. So a parent really needs to be aware of what the child is watching. TV becomes really bad when a parent uses it as a “robotic babysitter”. Just turn it on so it will keep the kid mesmerized all day…devoid of physical activity or personal interaction. It’s all about how you use the tv.
