Original Receipts 

Saturday, November 21st, 2015

I am a member of an organization whose Finance Committee has been advised to require "original receipts" for all reimbursement requests (and also for "gifts in kind"! But I'll get to that second bit of nonsense later).

Now it should be obvious that the idea is made ridiculous by the fact that most vendors will happily print out a second copy of the "original" receipt if requested (and that these flimsy items typically fade to invisibility within just a few months anyhow!), but for a bit more authoritative response I tried a Google Search.  And what did I find?

Original Receipts For Expense Reimbursement Policies


We are looking at eliminating the requirement of obtaining all original receipts. We currently require original receipts and scan these into our systems.

to which a typical response was "we are living a new world here, where most of the actual receipts will be in fact be mere printouts from the computer. For example, you have electronic air tickets (even for international travel), hotel bills are also printed on plain piece of paper, etc. This will be the majority of the travel expense. Hence, in such a situation there is no sense in actually collecting the original receipts as it will be the same as the scanned copies printed out."

Why Asking for Receipts Is Old School…. - Oversight Systems


Nov 25, 2014 - Original expense receipt requirements are an old school approach to expense control. In fact, I saw a recent list of the top five reasons why ...

Does the IRS accept scanned receipts for tax write-offs ...


Dec 22, 2010 - The rule that supports scanned receipts is called Revenue Proclamation 97-22. The rule states that scanned receipts are acceptable as long as they are identical to the originals and contain all of the accurate information that are included in the original receipts.

But when it comes to the taxman we certainly do need to obey the rules!

Of course, original receipts (whatever that means) are necessary where required by law - and in such cases it doesn't matter that the requirement is stupid. But in situations where the use is just for record keeping (and especially if the scale of he enterprise is small enough that duplicate submissions would be easily identifiable) they are completely unnecessary. And it is certainly clear that their requirement is by no means a universal or even "standard" accounting practic.
Two personal experiences contribute to my disdain for the idea that "original receipts" are in any way useful. One, from my professional life, involves a compulsive thief and liar who produced a cleverly forged "original receipt" to cover up a theft which was only discovered and proved by other means (after which a more careful examination did identify physical evidence of he forgery). And another from volunteer work in which "original receipts" were provided for items which were similar to, but of higher value than, those made available to the organization (and again, it was only after the fraud had been identified via a larger pattern of suspicious behaviour that the differences in model number were noted).

Mythical Myths #47-50 Spinach&Popeye

Wednesday, November 18th, 2015

This is cool because it has several components. That the iron content of spinach is a myth is itself a myth is just the starting point of a fascinating investigation of a number of related myths about how the confusion first came about and then came to light (some of which are themselves actually true and so only mythically myths). Thanks to Mike Sutton who may well be the world's champion in identification of mythical myths.

A story started thirty years ago by nutritionist Professor Arnold Bender, and famously supported by the immunohaematologist Professor Terence Hamblin, that a decimal point error made in 19th Century research of the iron content of spinach led to its erroneous promotion, is completely untrue.

"Good Reasons"

Sunday, November 15th, 2015


In a review of Vaclav Smil's books on global energy use, Tim Maly at The Atlantic, after explaining the virtual impossibility of transitioning to low energy density primary power sources in time to avert potentially catastrophic global warming, tells us that:

We know how to make nuclear reactors and hook them up to the grid, but Americans just don’t want to do it anymore. And there are good reasons for this!

So, the only transition away from carbon combustion that can occur quickly enough to save us from significant warming is the transition to nuclear. But hey, there are "good reasons" not to go that route. So I guess we'll just have to run the 4 degree experiment and see who survives.

or as commenter 'Theoretical Conspiracist' put it more politely:

A nonsense, throwaway sentence like this really mars an otherwise excellent article. I say that not to deny that there are "good reasons" for the policy/political resistance in America to nuclear power, but to remark on this odd, defensive, kneejerk inclusion of that "Hey, not that there's anything wrong with that!!" aside in an article whose overall conclusion is that neither the Republicans nor the Democrats have been honest or realistic about climate change and energy policy yet.

Since nuclear retains the existing grid infrastructure and has improved energy density (vastly advantageous to wind and solar), we really ought to be doing more to consider nuclear as a clean power source, perhaps as a transition to that far-future renewables infrastructure. We ought to interrogate the so-called good reasons and weigh them honestly against the alternatives rather than just handwaving briefly and moving on toward an otherwise terminal dilemma.

Do Pigments "Have" Colour?

Sunday, November 8th, 2015

A recent article in The Atlantic piqued my interest but left me very much unsatisfied as to what, if anything, underlies the "pantone" system. So I decided to Google for more info.

The second reference I found was a lot quicker and less "gushy" in getting to the point (or at least to the point that I was interested in), but only slightly more informative.

And the third was clearer about the Pantone distinction - in that it identified the Pantone system as involving many more different pigment types than CMY. But in the end it too failed to fully explain why more than three are needed (and why no finite set, including the Pantone system itself, can ever be "perfect").

In fact any colour experience can be reproduced with just the three signals corresponding to our three kinds of cone receptors, so the RGB system is capable of producing a light to match any colour that we can ever see.

But that's the colour of light, not of an object or pigment.

In fact, no actual thing we see, whether object or pigment, actually "has" a colour. It is light that has colour and what pigments do is modify the colour of the light with which they are illuminated by subtracting more of some frequencies than others. The colour of the reflected light then is what we see, but this depends both on the properies of the object and on the spectrum of the ambient light. Since lights of quite different detailed spectrum can produce the same RGB signals in our eye, and there are many different detailed subtractions that can take a given "white" light to any particular value of the RGB signals, it is both possible to have the same pigment look different under two "white" lights which we cannot tell apart and to have  two pigments which look the same under one light and different under another - even when the two lights seem to us to be exactly the same. This last is the real weakness of the Pantone Matching System. Unless one is just comparing with other Pantone products, a matching that works under one light might not work under another.

Is Bio-Degradation of Plastics Really a Good Thing?

Saturday, November 7th, 2015

According to conventional wisdom (as expressed in 'Seriously,Science?' at discovermagazine.com):

We all know that plastic is generally terrible for the environment because it doesn’t biodegrade, and just sits in landfills.

But why is having carbon locked up in relatively small known locations (rather than oxidized and maybe even methanized into the atmosphere and/or distributed widely in micro-particles of unknown toxicity) to be considered as "generally terrible for the environment"?

Can neuroscience explain consciousness?

Friday, November 6th, 2015

I think I would define consciousness in purely computational terms and I don't think I'd make it dependent on the specific structure in which the computation takes place.

eg, perhaps: "An entity is said to be 'conscious' if its state changes according (at least in part) to a computational process in which the input data includes a partial model of the state of the computational process itself."

This Shameful Tactic Cannot be Allowed to Succeed

Saturday, October 10th, 2015

Dear Conservative Canadians,

I share the fear of masked figures that is common in our culture, and I am more inclined than most to be put off by overt displays of religious and other affiliation. But the attempt to reduce  our political debate to the level of such feelings is so shameful that it must not be allowed to succeed.

For many the niquab is an imposed symbol of male domination, but for others it is a choice based on feelings of religious commitment or maybe even just on a learned sense of what I would consider excessive modesty. But however little I empathize with the particular motives, the idea of forcing a woman to reveal herself when she does not want to feels like a kind of sexual assault.

As conservative commentator Andrew Coyne has pointed out, over the past  years there have been just two women who felt unable to expose their faces in public an so were permitted to do so in private rather than during their actual citizenship ceremonies.

The cynical attempt by our current ruling party to make an issue of denying such women the right to citizenship without public violation of their privacy is something which will disgrace all of us if it is successful - or even if it seems to have been successful. So it must be made to fail.

The biggest factors contributing to our economy are external, and the actual differences between our parties on economic issues are minor compared to the harm that could be done to our social fabric by this kind of xenophobic bullying. So if you can't bring yourself to vote for any of the alternatives, then please just stay home on the 19th. Don't shame yourself by supporting the man who would make us a nation of small-minded bullies.


Our history proves why racial and religious division is dangerous.

Can the UN Combat Climate Change and Also Provide Energy Equality to All?

Wednesday, September 30th, 2015

From Charles Kenny of  the 'Center for Global Development', writing in The Atlantic:

Those who are anti-coal, anti-gas, anti-dam, and anti-nuclear when it comes to energy development in the developing world are implying that people there shouldn’t use electricity at nearly the level or low price that Westerners do. This, in turn, denies people safety, security, longevity, and comfort.

From 'axe the tax' to 'climate consensus': Looks like Bill Tieleman has more to answer for than just his shenanigans here in BC

Wednesday, September 16th, 2015

From Alex Frankl in The Guardian (referring to Tony Abbot's anti-environmental success in Australia)

"After years running focus groups I’ve learned one thing: technical terms like ‘carbon’ and ‘emissions’ can never win against a simple story about tax"

except here in BC where Tieleman invented this regressive "populist" message and managed to turn it into a (well-deserved) loser for the NDP.

Philosophy Has a Problem With Expertise

Hyperbolic and exponential discounting

Friday, April 10th, 2015

In his post on Hyperbolic and exponential discounting, Murray Bourne objects to the comment by 'kissmetrics' in Six Advantages of Hyperbolic Discounting that "the phrase hyperbolic discounting is despicable jargon".

But actually I tend to agree with that judgement - though not to the credit of the 'kissmetrics' author. ...more »

France Leads Again!

Friday, March 20th, 2015

France has log been a leader in finding and using alternatives to Carbon combustion, and also in legislating against potentially dangerous extraction schemes such as fracking. And now that solar technology has become cheap enough to make sense in many contexts, France appears ready to back it with legislation rather than bribes.

But in the article France Says New Roofs Must Be Covered In Plants Or Solar Panels (at ThinkProgress), ends with a weaselly remark that "France has lagged behind other major European countries like Germany, Italy and Spain in solar power development. As of last summer, France had just over five gigawatts of photovoltaic capacity, accounting for around one percent of total energy consumption. Germany has nearly 40 GWs installed. France is heavily reliable(sic) on nuclear power for its energy, and nuclear generation in 2012 made up about 83 percent of the country’s total generation." So Germany's solar effort, being about 8 times that of France, displaces about 8% of its Carbon combustion - which France has beaten by a factor of ten by going nuclear. Some laggard!

Finland Understands Fairness in Punishment

Friday, March 13th, 2015

Finland, Home of the $103,000 Speeding Ticket — The Atlantic.The clearest case for this is in cases where there is a fine or jail time option. Why should the poor suffer loss of a much greater fraction of their entire lives than the rich for the same offence? But total assets should figure in as well as current income, and the same principle should apply to corporate wrongdoing - with the penalty being conversion to the state of a fraction of total equity (including voting rights) comparable to whatever the jail term for the same crime would be for a guilty individual as a fraction of an average expected lifetime.

How to Live Like a Stoic

Wednesday, March 4th, 2015

Massimo Pigliucci has a new blog about his experience of following a "stoic" philosophy.
My goal in following Massimo is not to become a Stoic but just to get a better understanding of what it means, and in particular how the attribution to Stoics of faith in the Logos squares with the often expressed idea that they didn’t hold to an objective moral law.
As one who strives to live "according to positive values” but “reject the idea of an objective, universal and unchanging moral law”, I don’t see any contradiction there. But given how often people claim to see one, I will be interested in leaning more about how the classical responses to that perception compare to my own. ...more »

What does the "Many-Worlds Interpretation" of Quantum Mechanics even mean?

Saturday, February 21st, 2015

Sean Carroll identifies some Wrong Objections to the Many-Worlds Interpretation of Quantum Mechanics, which is fine but I'd rather he addressed some of the better ones.

I have always thought of (my own experience of) the universe as corresponding to (a very small part of) one particular configuration of a stochastic system, and that having a theoretical model for that system allows me to predict conditional probabilities of certain features (measurements) given others (state preparations). I suppose other configurations could be regarded as alternate worlds which *could* in some sense exist. But why is it necessary (and in fact, what would it mean) to suggest that they *do* exist?

Oh dear! Now I feel a little Feynmanesque "poem" coming on:

We don't know the meaning of "meaning",
And we don't know the meaning of "is".
So how can we possibly claim to know
What the meaning of  "the meaning of "is"" is?

What's in a Name?

Sunday, February 8th, 2015

Shadi Hamid and William McCants (of the Brookings Institution) object that "John Kerry Won’t Call the Islamic State by its Name Anymore". The article contains two arguments, the first very bad and the second very good.

The good argument is that no non-Muslim has any business dictating what is or is not "true Islam". It may be fine to report on one's understanding of what the majority of Muslims seem to be saying on the matter, but to put that in the form of an authoritative declaration is both patronizing and ridiculous.

But the idea that this forces one to accept the self-declared "name" of an organization is also ridiculous. If the LRA had decided to call itself "Christians of Africa" would anyone seriously think it appropriate to go around saying "the Christians of Africa must be destroyed"? Of course it is appropriate to refuse ISIS the dignity of calling it "The Islamic State", and indeed to accept that designation is an insult to the many Muslims who do not accept it as such. (But of course this refusal can and should be done by reference to the requests of other Muslims rather than to one's own position on what is "true Islam".)


More on Zealotry

Sunday, February 8th, 2015

The proper response to Islamic Zealotry (including some criticism of Walzer's position) has also been discussed (again in 'The Atlantic') by Shadi Hamid with particular reference to the situation in France.

Hamid points out some of the real inconsistencies in the French (and much of the European) position, but his analysis also seems to me to be dangerously off-base in some respects.

Christians Enraged by Obama's Failure to Demonize All Muslims

Friday, February 6th, 2015

Apparently the conservative pundits and right wing religious types are all excited about President Obama's having mentioned that using religion to brutalize other people is neither a Muslim invention nor foreign to the American experience.

According to ThinkProgress, Russell Moore, President of the Southern Baptist Ethics and Religious Liberty Commission, said, “The evil actions that he mentioned were clearly outside the moral parameters of Christianity itself and were met with overwhelming moral opposition from Christians.” Would that be the same Southern Baptists whose very raison d'etre was to split off from the main Baptist Church in order to allow their preachers to be slave owners (and who continued resisting integration right through the 1960's)?

The Media analyses Varoufakis' wardrobe

Wednesday, February 4th, 2015

The European has an article on the new Greek finance minister - which apparently picks up on a report in The Guardian. There is also news about his discussions with Osborne and other Euro finance ministers but in a profile of the man I would have liked to learn more about his economics background. Anyhow I guess it's nice to see even just one example of a male politician being discussed largely in terms of his appearance and clothing.
