"Moxon's Master" by Ambrose Bierce. Question and Answer Analysis.



Exercise:
Question no 1.
Answer: Moxon's definition of a machine is taken form a popular dictionary. According to this definition a machine is "Any instrument or organization by which power is applied and made effective, or a desired effect is produced". Moxon extended this definition to man too. he also says that by virtue of the fact that machine is created by man, it absorbs something of man's intelligence and purpose. Thus making it sentient, living, feeling, conscious being.
I agree with the definition from the dictionary. I believe that machine in terms of being an automaton is a device operable by man. However I do not believe with Moxon's extension of the definition to automatons as being alive, feeling, conscious beings.

Question no. 2.
Answer: Moxon is developing a sentient conscious machine, one that can think and possesses intelligence.
Moxon believes that no matter is inert or dead. It is ll instinct with force; actual and potential. He believes that all matter is sensitive to the same forces in environment as man himself. When matter comes into contact with man: when he is fashioning it into an instrument of his will, it absorbs something of his intelligence and purpose. This absorption is greater and depends upon how complex the resulting machine is. Based on this theory, Moxon is developing a machine which he believes will be capable of thinking, acting and possessing consciousness- a robot or automaton which will be able to perform actions independent of it's creator.

Question no. 3.
Answer: Plants have a mechanism for performing different activities. They show movement under the influence of light. Some plants are sensitive to touch. Some can trap insects to meet their nutritional needs. However this does not mean that plants can think. plants do not have a nervous system. If they did their faculties would be comparable to either animals or humans. They would then have been able to perform actions like higher animals. Thus, there is no space on an argument on the question whether the plants can or cannot think.

How to attempt a paper.

Physics second year paper short question answer.
Physics paper second year.
No matter how well you study, it is very important how you attempt a paper. There are people who learn every thing by heart. Every single bit of detail is ingrained in their minds yet they score less than some mediocre students. The reason? Those of you who have already given an exam with the Peshawar Board or even any other Board of Khyber Province, you would know that the performance is solely judged on the way you attempt your paper, how well your handwriting is and how neat your over all paper looks. Some may say that it is a sub standard method of education, but guess what no one is bothered with your opinion. Your opinion apart, you are attempting the Exams from this center so you need to understand what you are facing before you enter the Examination hall.

*You can use either a black or a blue marker for headings or even a black pointer would do. Make the headings prominent and also the sub headings and definitions.
physics first year paper.
*Never use an ink pen while doing a paper. I know you can use an ink remover but this is still a great risk. The ink could be washed away and there would be no evidence left of your work. Also the ink color of a dollar pointer pen is much batter than an ordinary ink pen. This may sound impossible to some raising questions like: But what if I make a mistake and have to write something down?
Well the answer is this that you don't make a mistake in the first place. If you try practicing this in your home exams it will not be a problem in the finals. However if you do make a mistake with a pointer you can always cut it with a pencil, not even with a pen cause it would make it more prominent.
Physics first year paper.
*Make drawings and diagrams with all short and long questions of Chemistry, Physics, Biology.
*Use a pencil and a ruler a lot. Make the margins with a pencil. I have seen people use pens for that but that looks so out of place. NEVER EVER USE A PEN OR MARKER FOR DRAWING MARGINS.
*To make the formulas or reactions prominent in Physics and Chemistry use a black pen, a different color than the normal blue text.
* Always label the diagrams. There is nothing more offensive than unmarked, unlabeled diagrams. Don't even bother drawing a diagram if you don't have enough time to label it. It looks like some idiot stupid trying to impress the examiner with out even knowing enough about the question.
*Always choose the simplest questions first, the one's you know by heart cause you are bound to write those neatly and the beginning of a paper MUST be very VERY neat.



Exam Advice.


Isolated system exam advice.
  1. Revise the entire syllabus. Don't focus you attention on your favorite subjects or important topics only.
  2. Practice and go through as many past papers as you can.
  3. Do extensive study and practice. Remember nothing can be achieved without commitment and hard work.
  4. You need an excellent time management strategy.
  5. Remember no one is going to care whether you complete your lesson or not. You have to put checks and boundaries on yourself. If you are going to start studying seriously, you need to gather up every ounce of will power and not be tempted or lured by any sorts of temptations around, especially during the study hours.
  6. Try to read quickly, actively and avoid missing a single detail.
  7. Revision of everything which you have learned is must so that it stays put in your mind.
  8. Analyze yourself and answer these questions:
  •  Do you learn better in the early morning? 
  • Do you need to hear something to remember it?
  • Do you need to write something to remember it?
  • Do you feel better to keep a drink in company?
  • Are you good at combined study?
  • Do you learn things in quiet and cozy places?
Happy Studying !!!

Alternation of Generation: Metagenesis.

Alternation of generation...Metagenesis.
METAGENESIS:
DEFINITION:
"The alternation of generation that reproduces asexually (by budding or fission) with a generation that reproduces sexually (by eggs and sperms) is called alternation of generation"
FOR EXAMPLE:
Coelentrates like Obelia.
EXPLANATION:

  1. Obelia colony does not bear gonads and is therefore sexless representing asexual reproduction.
  2. It develops by budding and is diploid.
  3. It contains three types of zooids: polyps and medusae.
  4. Polyps reproduce asexually by budding to give medusae.
  5. The medusae are set free by the parent colony and swim in water. It is free living.
  6. The medusae give rise to egg and sperms - acting as reproductive organs.
  7. On fertilization the oosperms again develop into an asexual obelia colony.
CONCLUSION:
Free type swimming medusoid sexual alternate with sessile polypoid asexual.

Error, uncertainty, precision and accuracy.

Question no. 6
Define the terms error, uncertainty, precision and accuracy.

ERROR:
DEFINITION:
"The difference between the measured value and the actual value of a measured physical quantity is called error."
EXPLANATION:
Error can not be less than the least count of the measuring instrument.
There are three types of errors in the measurement of physical quantities: personal, systematic and random.
There are certain kinds of errors that can not be removed.

UNCERTAINTY:
DEFINITION:
"The error arising due to the natural imperfections of the experimenter, the limitations of the apparatus and changes in the environment during the experiment is often called uncertainty."
EXPLANATION:
It is described as the error in the measurement.
There is always an uncertainty in the measurement.
It is used to express the uncertainty.

PRECISION:
DEFINITION:
"The term precision stands for magnitude of the error in the measurement."
EXPLANATION:
Precision of measurement is determined by the instrument being used.
Precise measurement is the one which has less absolute uncertainty.
The smaller the physical quantity, the more precise the instrument should be.

ACCURACY:
DEFINITION:
"Accuracy stands for the relative error. It is defined as the error divided by the quantity measured."
EXPLANATION:
It depends on the fractional and percentage uncertainty in that measurement.
Accurate measurement has less fractional or percentage uncertainty.

Pakistan Studies in English For Second Year Students.

Pakistan Studies In English. Books for second year students.
As the students of second year start with the year, those of them having Pakistan Studies in English are pretty worried. Thanks to Peshawar Board we don't have an official textbook. There are many guides of course to help through the way. Here are some which I recommend to you...


  • N.W.F.P Text Book Board Book: The Urdu official book is very important for objectives. No matter how much you learn the translation of it, there are always things missing. So remember to keep in touch with the Urdu book for objectives. Read every chapter, highlight things for objectives, underline the names, facts and figures and synchronize them with your guides. Most important chapters for this are Chapter 1, 3, 5 and 11. Others are also important, so don't skip any of them. I will not tell you the easy way out but the one which will ensure good scores.
  • Hi Vision Pak Study: by Amara Haroon and Miss Syeda. This book has loads of spelling mistakes and all but it is the translation of the Urdu textbook so I will highly recommend this. There were girls in our year who sat down to translate the Urdu book themselves but never finished. This book is also good for headings and the figures are mostly accurate.
  • Pakistan Studies Intermediate: by Dr. Abdul Qadir Khan. National Book Foundation Islamabad. I found this book very good and would again recommend it. No one I knew used this book much but I did. The language in this book is simple and clear. There are many topics missing and for those you will have to read other books but the topics it does contain are good, brief and clean.
(I will list the topics which are missing in this book later for your convenience)
  • Introduction to Pakistan Studies: by M. Ikram Rabbani. This book is used by many and is very extensive with details and all. I would recommend this book for important long questions only. The details in it otherwise would dazzle you to oblivion is all I can say.
  • Pak Studies Class 10: You can use this book too for common topics because you have already learned it once and it is way easier and less time consuming.
  • Star Social Studies Book 8: This book has awesome History section especially the Chapters:The Pakistan Movement : The three Era's. It is very good for long questions as well as short notes.
  • Quotes From the Quaid: By Oxford. The quotes from Mohammad Ali Jinnah are an essential part of Pakistan Studies and you can get all sorts of quotes from Jinnah in English from this tiny but helpful book.

System of units.

Chapter #1:
Physics and Measurement:
Short Answer Questions.

1. What is a system of units? List the basic Si units.

SYSTEM OF UNITS:
DEFINITION:
"A complete set of units both basic and derived for all kind of physical quantities is called a system of units."
HISTORY:
In 1960 an international committee agreed on a set of definitions and standards to describe the physical quantities. The system that is established is called the system international. Befor 1960 many system of units were in practice such as:

  1. British FPS system.
  2. MKS system.
  3. CGS system.
However with expansion of trade and the utilization of science and technology international system of units was adopted.
IMPORTANCE:
Due to the simplicity and convenience with which the units in this system are amendable to arithmetic manipulation, it is in universal use by the worlds scientific community and by most nations. The system of unit is made of three kinds of units:
  • Base units.
  • Derived units.
  • Supplementary units.
BASIC SI UNITS:
there are seven base units for various physical quantities namely length mass time, temperature, electric current, luminous intensity and amount of substance (with special reference to the number of particles)
The names of the base units along with their symbols for the physical quantities are listed:
