Baby’s First Klein Bottle™

Not only did it not fall apart in my hands …

first tangible result


The strand — for it is a Klein bottle woven of a single strand — is thinner than I expected, and has broken in at least two places. Ah well, live and learn; I’ve already redesigned it to be more robust.

don’t look now, but I’m a sculptor

I submitted a design to Shapeways today! I’ll tell you more if it doesn’t fall apart when I get it in my hands.

QotD

Do we not continually hear them quote Blackstone’s assertion that “no subject of England can be constrained to pay any aids or taxes even for the defence of the realm or the support of government, but such as are imposed by his own consent, or that of his representative in parliament?” And what does this mean? In affirming that a man may not be taxed unless he has directly or indirectly given his consent, it affirms that he may refuse to be so taxed; and to refuse to be taxed is to cut all connection with the state. Perhaps it will be said that this consent is not a specific, but a general one, and that the citizen is understood to have assented to everything his representative may do when he voted for him. But suppose he did not vote for him, and on the contrary did all in his power to get elected someone holding opposite views – what then? The reply will probably be that, by taking part in such an election, he tacitly agreed to abide by the decision of the majority. And how if he did not vote at all? Why, then he cannot justly complain of any tax, seeing that he made no protest against its imposition. So, curiously enough, it seems that he gave his consent in whatever way he acted – whether he said yes, whether he said no, or whether he remained neuter! A rather awkward doctrine, this. —Herbert Spencer: Social Statics

Woven Palette mugs

I’ve added several designs to my Zazzle store. They’re based on the concept hinted at in my last post.

Gray palette


I came up with this concept several years ago (I can’t tell exactly when, because I’ve mislaid the original code!) but never posted any of the images until now.

Some of you may like to guess what’s going on before I tell. For more hints, see these patterns’ 254 siblings.
