General Science / By how much does carrying extra weight affect car fuel economy?

« on: 16/03/2015 04:26:29 »

Hello all

I am doing a bit of traveling in my small 1.4 litre car (Hyundai excel). I have not weighed the content inside, but it may be around 150 Kg in extra weight. How much will this affect fuel economy, and is this weight burning out my car quicke? I do about 30 kg per day around town.

Do I look into physics for these answers ect.   (momentum)  Is there any math formulas to be used as a guide for vehicle per weight?

Thanks in advance.

Physiology & Medicine / Book help

« on: 16/11/2014 03:13:41 »

Hi all. Currently reading principle of anatomy and physiology by Gerard j Tortola & Bryan Derrickson 11th edition. This is a text book for first year students at university level. It has all the body system rolled into one and I am needing text book on individual body system, preferred from the same author. Not a big Google search person and prefer books.
 
Oh one more thing. I am using iPad and the web site keeps on freezing. Would this be at my end? Is any one else having this problem.

Thanks in advance

Thank for your reply

 Sound good to me.

Was thinking the other day that may be a personal wiki page on the net will be the way to go for this project and integrate it with file from internet and personal file on PC (dropBOX).

Getting organised is always the hardest step for me but once i get the rest is all down hill.

General Science / What's the best way to organise information?

« on: 22/03/2014 00:23:28 »

Hello all

I am a big follower of Dr karl and i here him say a lot that he has a 24 some meg file on a particular subject but he seems to have a lot of these single files on a subject. I would like to know some tips on organizing information on a wide variety of subjects, do i link them to the type of ~ology or by subject or give up together and just uses Wikipedia. 

I try to get them into folders but they tend to get very messy and unorganized, with a lot of double ups.

« on: 31/05/2012 04:05:52 »

Hello CliffordK

Thanks you for your lengthy reply and there is a lot of information that I can use as a guide. I did not know that Barack Obama received the Nobel Peace Prize, OMG. I currently am completing a degree in Occupational therapy. I love getting ideas and concepts that are beyond my level and trying to work out the best possible way of solving out these problems and a noble prize is one of these concepts. Even though it is beyond me I will still try.   

I think information and achievement is weird, Greek philosophers believed that the heart was the central organ in the body that was controlling the body. They were proved to be wrong but in the process of being wrong what they did was spark curiously so other can think and understand the body better and as technology got better so did understanding. I ask this question because I believe that as humans we can speed up evolution and be able to learn faster to keep up with knowledge by multi tasking more effectively or to read a book by just looking at the page. This sounds crazy but I like to ask what is the limit to human intelligence? I am thinking in 20 to 1000 years or possibly 5000 year. I am currently writing a paper/essay on this and will keep you posted on my finding.

Just Chat! / just introducing my self and background

« on: 13/05/2012 02:05:21 »

Hello my name is Satrah, love the show. I am currently studying Occupational Therapy and in my second year. Without be biased toward other disciplines, I believe that this is one of the best degrees in the world with a focus on doing within the occupations we choose and the role we play within the occupations. Occupation is the everyday ordinary things we do, some people are teachers, paints, mechanic scientists, students and the occupational list can go on and on. If I take student as an example, the roles would be touch typing on the computer, lessoning skills, hand writing note in lectures, completing assignments, communicating with others, asking questions, and many more. If a person has an injury of some sort or struggles with mental health issues, an occupational therapist can intervene and help with skills that are affected.   A lot of my questions that I will be asking in this forum will be around doing and how we do thinks in our everyday lives. This includes multitasking and is it possible to effectively perform this skill and complete a number of tasks at the same time.

I am fascinated by the concept of transferring skills from one task and applying it to other tasks or activities. For example touch typing, I learnt this skill at school and hated it. Computers were not common at homes and I did not see the point in doing it but when I left school I was watching some play the guitar and I saw a lot in common in the person playing the guitar and touch typing independent movement of fingers, so I bought a guitar. Later I joined the choral society as I saw playing the guitar notes were the same as sing. Once I got the practice of singing notes I bought a violin as I did not have frets like a guitar and I had to rely on my skills of recognising the sound of the notes though cord and scales. The breathing use in singing happens to be about the same as playing the flute so I bought a flute.

With limited time to play all these musical instruments I have decided to play some of them only 5 minutes of the day and I was surprised that within this time frame I am still making progress in learning.
In Occupational Therapy we are taught to perform a task analysis were activities that are performed are broken down in the steps were the activity cannot be broken down any more and sequence the steps in a logical form. As a result of lack of money to pay for singing lessons, I have decided to perform a task analysis on sing.  I have work out a person is only singing about 5 sounds and these are the sound of the vowels. I guessed that when we speech word normally the consonants is more prominent but with singing it is the opposite and the sound is dragged out over time.  With progression I have learnt to increase the volume and decrease it.  No songs are sung at this stage and I am still progressing in this quest of learning how to sing. I m not going to ever be able to sing at the Sydney opera house but I can still develop and learn as a person and gain the health benefits of doing and the positive aspects on my mental health.

Sorry for the spelling and grammar mistakes, this is still my weak point in writing.

Geek Speak / the speed of you computer

« on: 11/05/2012 06:27:07 »

Why is it that when a new operating system for windows come out it is said that the new system is faster that the pervious system. Is this misleading, as the new operating system requires or uses software that need new more RAM or more complicating software. This making it the same at the pervious operating system when it come to time speed. For e.g. the speed of starting your computer.

Physiology & Medicine / Re: Could the immune system be used to help cure cancer?

« on: 11/05/2012 06:12:07 »

Hello thedoc, I don’t know the answer for this question but what I do know is that it is possible to live to 104 and be cancer free. I meet a lady who was this age and she had her full mental facilities and cancer free, this was confirmed by nursing staff. So under the right condition is it possible for the body to fight off cancer but must have a strong immune system. From what I have been reading in my anatomy and physiology text book on the immune system it is possible for the body to find and kill cancer cell, I am still looking in to this phenomenon and I will keep you update. Hope this makes sense.

General Science / Is sight-reading music multi-tasking?

« on: 10/05/2012 13:26:12 »

Is learning how to read music a form of multi tasking, a person has to perform many tasks at the same time. Visual skills to look at the music notes and to recognise the rhythm, proprioception to know where your arms, hands and fingers of both up limbs are in space, hearing to learn the rhythm, posture of body, death perception to know how much pressure to place on the sting fret with multiple fingers, independent use of fingers and memory. These have to be performed at the same time for everything to work so that one can learn how to read music and develop the skill. However, these skills are learnt at one stage at a time e.g. to start off slowly and get it perfect, then increase speed, plucking of all six strings on the right hand first in progression and the rest is graded in the difficulty of level. I am not an expert on reading music but have learnt the basics.  I would like to know can the setting of this single task of reading music from guitar be changed to other areas. Is it possible to lesson to the radio (the naked scientist) and read a book at the same time and understand both? we cannot control the radio speed in which they talk but can with the speed of reading and  to get it right start off very slowly, increasing speed and get both right. I have tried this but my reading speed is very slow but I can understand both and sometimes I have to re read the sentence.
If this is true how many other tasks can I add or change

•   Singing opera musicals of lecture notes from uni e.g. anatomy and physiology, physics
•   Cleaning while singing lecture notes in opera
•   Have the radio on (the naked scientist) while cleaning, singing lecture notes in opera.

I’m guessing that this type of skill will not develop over night and may take a while

Hope this make sense it’s only a theory that I have

Just Chat! / needing study tips

« on: 11/12/2011 13:23:27 »

Hi everyone
 
I am posting to get some tips on studying as I am in my second year of my degree as an Occupational Therapist and need some help as my memory is not the best. 5 years ago I quit the consumption of alcohol as I was a 12 year alcoholic and I drank just about every day. I don't know if this has had any long lasting effect on my memory. The strategies that I have formed so far have come about through observing other people that have a high level of intellect.  Most of these people are very good spellers that can spell very quickly. Smart people tend to remember players names when watching the football and the same as actors names and what movies they were in. singers in musicals have a good memory to process both singing and movement dance at the same time.
I have come to the conclusion that the brain process speed can be increase by doing certain brain exercises, these are of few of the exercises that I do:

•   Spell out work to myself when I am out for a walk, look at the word, spell the word, and then look back to see if I got it right. (This has helped big time for my spelling).
•   Try to remember name of the players when watching the football (Go the cowboys)
•   Keeping a hand written dairy.
•   Puzzle books like crosswords
•   Have a study word list to remember, the more study word list the better my processing speed will be and the quicker I can remember list e.g. list the muscles of the arm, or part of the brain
•   Always using a dictionary to build up my vocabulary
•   Because I am studying anatomy and physiology, learn the suffix and prefix
•   Study different areas in general knowledge (politics, music, history)

With spelling I have found that if I spell the word to rhythmic time where I don't make any mistakes, I find that it if easier to remember, this goes as well to list of words to remember, once I can say the list out loud confidently in can remember it easily but this takes some time.

I saw a young child a little while back. I was in a bank and the she counted all of the people in the line up and went back to her mom a said excitedly theirs 22 people in the line. I realised that he young child was learning so I have adopted this style of learning. When I go for a walk to the shops I have lecture notes from uni and study them.  I really want to complete my degree if any one has any study tips can they please post them here.
Thanks

Geek Speak / changing the backspace button format on computer keyboards

« on: 11/12/2011 12:12:12 »

Hi all

Would like to know who do i see to change to computer keypad format on computers. When touch typing it would be easier if the backspace button was closer to the  J K L : area. So the new place for it would be the {} [] buttons to the left of P and not at the corner of the keypad.

Question of the Week / QotW - 09.05.24 - Will the stupid outbreed the clever?

« on: 11/12/2011 05:30:55 »

Having a high level of intelligence does not make a person a superior person for breeding. I have lived with university students doing their masters degree and lack in fundamental life skill: student number one. I watch this student for two weeks trying to ride a pushbike in the backyard with half flat tyres and going in 3 meters circles and falling off repeatedly. Student also doing masters cannot use a screw driver at all he passed it to me and said “can you do”. Student 3 doing masters in Information technology needed help with knowledge on virus protection and how to reinstall windows operating system.  OMG how did these people get in to uni

 I have lived with drug users and alcoholics that had kept the house cleaner then these people. Just because people are at university does not make a person educated it just means they have meet the basis requirement to get into university. Just because a student has completed their university degree does not make them qualified, it only mean they have complete the basis requirement to complete the course.

I have been told all my life that I have to be smart to get in to uni. Now I am in my second year of uni.  5 year ago I could hardly read or write. So be kind on my grammar skill, I’m slowly getting there .
