U las de titel van dit boek en vulde spontaan aan met '... denkt een man aan seks'. Waar of niet? Toch zeggen de woorden 'Elke drie seconden' niets over seks, maar wel alles over wiskunde, want drie seconden is een maat en meten hoort thuis bij de koningin der wetenschappen. Deze vaststelling nodigt uit om verder na te denken over seks en wiskunde. Als we wiskunde bepalen als het zoeken naar patronen en structuren en als je aanneemt dat alle menselijke activiteiten patronen vertonen, dan moet ook ons seksuele leven door een wiskundige bril kunnen bekeken worden. Dit boek brengt dergelijke patronen samen. Wat hebben reproducerende konijnen met de gulden snede te maken? Bestaat er een strategie om de ideale partner te vinden? Wat zijn de mathematische grenzen van datingsites? Hoe kan de (ingewikkelde) dynamiek van een relatie beschreven worden? Hoe verspreiden soa's zich? En waarom garandeert meer seks veiliger seks? In Elke drie seconden komt veel wiskunde voor, maar het wordt zo gebracht dat geen voorkennis vereist is. Zo wordt het boek een dubbele ontdekkingsreis: de seks zal na dit boek nooit meer dezelfde zijn en de schoonheid van de wiskunde zal zich blootgegeven hebben, een opwindend vooruitzicht!

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs. The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily. Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.
