It feels like a long time since the first one

I don't think I could calculate how long it's been, in fact. But the Mental Calculation World Cup is still going strong! Here's the invitation to compete, if you want to test your brains!

Mental calculators from all over the world are invited to the 8th Mental 
Calculation World Cup 2018!

The Mental Calculation World Cup 2018 will be held in Wolfsburg, Germany
========================================================================

Venue: Science Centre Phaeno (http://www.phaeno.de)

Date: 28-30 September 2018

Contest Details:
Calculators will have to solve tasks in different categories (addition, 
multiplication, extracting roots, day-of-the-week calculations) and 
various surprise tasks.
Only strict mental calculation (no tools, no writing down of 
intermediate results) is allowed.

Prizes:
There will be several titles and trophies for the best participants.
In particular, the MEMORIAD Association will sponsor free flights to the 
MEMORIAD 2020 competition (planned to be held in Dubai, USA) 
(http://www.memoriad.com) for the winners in the categories addition, 
multiplication, square roots and calendar calculation as well for the 
winner of the combination.
(does not apply for participants who are not allowed to enter MEMORIAD 
contests according to decisions of the MEMORIAD Association).

Registration:
The registration form can be found on the MCWC web site 

Calculators who already took part at a previous MCWC event are welcome 
to send the application form by e-mail to info@recordholders.org.
First-time participants please download the entry form on the MCWC web 
site. Please send it by airmail together with the documentation that is 
necessary for qualification to the address given in the form.
Please note that we have a tough qualification (with usually far more 
than 40 people registering). Calculators who took part in one of the 
previous years may want to send additional documentation about their 
recent results in the same way as the first-timers (by airmail with all 
the paperwork) in order to have better chances in the qualification.

Deadline for Registrations: 1 June 2018
You can help us with the organization if you register soon.

Qualification:
The number of participants is limited to 40. If more people register for 
the event, the organizer will select the participants who qualify. For 
this purpose, information about previous results at mental calculation 
events (achieved in the past ten years), other mental sports contests 
and verified achievements with the Memoriad software 
(http://memoriad.com/memoriadsoftware.asp) are taken into consideration.
The results achieved should be documented (category, number of correct 
answers, time) and sent together with the application form. These 
results must be confirmed by a witness with some background in mental 
calculation (for example a maths teacher or a university researcher who 
works in a field close to mathematics).

Organizational stuff:
There is no entry fee, but participants have to pay their travel 
expenses. We will publish hotel recommendations soon enough on the MCWC 
web site.

Please contact us soon enough if you need a formal invitation letter for 
visa purposes. Keep in mind that in some countries visa formalities can 
take a long time!

More information can be found on the web site:

Contacts:
If you have any questions on the MCWC, please contact me at 

I am looking forward to meet the world's best calculators in Wolfsburg!

I should get some kind of prize

I was just about to go to bed for an early night, when I remembered I hadn't written a blog entry, and if I did that, then I'd break all kinds of world records for keeping new year's resolutions. So now I've accomplished a whole week of daily uninspired short paragraphs, I can rest easy and not write anything more for whole months at a time if I feel like it.
