Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the ability to do things well, successfully, and without waste. In more mathematical or scientific terms, it is a measure of the extent to which input is well used for an intended task or function (output). It often specifically comprises the capability of a specific application of effort to produce a specific outcome with a minimum amount or quantity of waste, expense, or unnecessary effort. Efficiency of course refers to very different inputs and outputs in different fields and industries.
Efficiency is very often confused with effectiveness. In general, efficiency is a measurable concept, quantitatively determined by the ratio of useful output to total input. Effectiveness is the simpler concept of being able to achieve a desired result, which can be expressed quantitatively but doesn't usually require more complicated mathematics than addition. Efficiency can often be expressed as a percentage of the result that could ideally be expected, for example if no energy were lost due to friction or other causes, in which case 100% of fuel or other input would be used to produce the desired result. This does not always apply, not even in all cases in which efficiency can be assigned a numerical value, e.g. not for specific impulse.
Jean-Luc has ideas about how to live your life more efficiently in this fast paced world. Of course, books and websites offer many tips on how to be more productive, but, perhaps, too many for us to absorb. To bring all these tips into a coherent strategy, he proposes a simple but solid model; through his talk he will illustrate this model in action with a diversity of examples and personal anecdotes. Engineer and PhD in applied physics and founder of Principiae This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Last ditch effort to try and explain why doing the best thing is usually the best thing
During this lecture I will talk about something that I think is extremely interesting: What is efficiency? It is a term that everyone uses, but very few understand. I would argue that 98% of all organizations have an incorrect understanding of what “true” efficiency really is. We tend to over focus on individual and functional performance. We think that efficient “islands" is a good thing. The more we deliver the better! The problem is that research shows the exact opposite! The more we try to squeeze out from the different islands within our organization, the more inefficient the organization will be! So what is the conclusion? Being “busy” is BAD! We call this the efficiency paradox! During this lecture I will describe why this phenomena occurs and how we have to redefine our view on eff...
Calculating the efficiency of a low energy light bulb.
Everyone wants more time. Efficiency is one way of adding minutes or hours to your day. Here are eight tips effectively used by the most efficient. 1. Stop Multitasking Many people fool themselves into thinking they are good at multitasking. Actually very, few can solidly focus on more than one or two tasks, particularly if they require focus and depth. Efficient people know that concentrated effort with few distractions leads to better work product in faster times. Otherwise, the work may not be up to par, which means wasting even more time and energy going back to fix the mistakes. 2. Delegate So much productivity is lost when people take on more than they can accomplish. Do not be inspired by CEOs and leaders who overload their schedules and burn the midnight oil. Efficient people are e...

Consumers, Producers, and the Efficiency of Markets lecture
Parody of "The Reason" by Hoobastank
(Ephesians 2:5-10; 2 Timothy 1:9; Titus 3:4-7; Galatians 2:16, 21; Romans 4:16, 5:2, 5:8, 11:5-6)
I'm not allergic to workin'
But many things religious people do
Are cause they think they're earnin'
A Heaven they must work their way into
But no one has to pay before they go
The Bible wants you to know
I've found salvation is free
And changed how I view good deeds
From readin' I started to do
In Ephesians chapter 2
It's not about our virtue
It's something that's a gift we get through grace
And all the things for good you do
Are just the icing you put on the cake
Ephesians 2:8 makes all that clear
That's why I'm leading you here
I've found Ephesians to read
It changed why I do good deeds
Salvation is not what we do
Are you readin' it too? Are you readin' it too?
Are you readin' it too? Are you readin' it too?
Another perfect person
Was Heaven-sent to do those things for you
And so no one who's saved can ever boast
In any one but the Lord
I've found salvation's a tree
And faith's what you use for seed
But grace is the start of the roots
And good deeds are just fruit
1:9 Second Timothy shows
And Titus 3:5 says it's so
And Romans provides added proof
In 11:6 too
Ephesians 2:8-10
